Fixes#3452.
With the change of data adapter, we have configured adapters for tags and tokenizers.
We also renamed the method onDemandLoad to showOnScroll to avoid confusion.
2) Fixed minor issue where we use dialog tab navigator keyboard shortcut only on visible tabs.
3) Fixed an issue where Zoom in, Zoom out, Zoom to original and Download button should not blur the focus after a click on them.
Initial patch sent by Murtuza Zabuawala.
2) Fix server connection drops out issue in query tool. Fixes#4818
3) Fix VPN network disconnect issue where pgAdmin4 hangs on expanding the Servers node. Fixes#4926.
4) Ensure that the Servers collection node should expand independently of server connections. Fixes#4933.
Set the default connection timeout to 10 seconds instead of 0.
1) Suppress ESC key presses in Alertify dialogues when the come from Select2 controls (It also closes the alertify dialog when user try to close Select2 using ESC key)
2) Do not allow Tabindex focus on Switch control when it is disbaled
3) Tab keyboard shortcut navigation does not work in wcDocker iframe.
Fixes#4935
2) Added Dark(Beta) UI Theme option. Fixes#3741.
3) Fix an issue where a black arrow-kind image is displaying at the background of browser tree images. Fixes#4171
Changes include:
1) New theme option in preferences - Miscellaneous -> Themes. You can select the theme from the dropdown.
It also has a preview of the theme just below the dropdown. Note that, a page refresh is needed to apply changes.
On saving, a dialog appears to ask for refresh.
2) You can create your own theme and submit to hackers. README is updated to help you create a theme. Theme will be available only after the bundle.
3) Correction of SASS variables at few places and few other CSS corrections.
4) Added iconfont-webpack-plugin, which will convert all the SVG files(monochrome) used as icons for buttons to font icons.
This will allow us to change the color of the icon by using CSS color property.
5) All the .css files will bundle into a separate file now- pgadmin.style.css. This will help reduce the size of
theme CSS files as CSS in .css files will not change with the change of SASS variables.
Changes include:
1) Remove underscore-string and sprintf-js packages as we were using only %s. Instead, added a function to do the same. Also changed gettext to behave like sprintf directly.
2) backgrid.sizeable.columns was not used anywhere, removed. @babel/polyfill is deprecated, replaced it with core-js.
3) Moved few css to make sure they get minified and bundled.
4) Added Flask-Compress to send static files as compressed gzip. This will reduce network traffic and improve initial load time for pgAdmin.
5) Split few JS files to make code reusable.
6) Lazy load few modules like leaflet, wkx is required only if geometry viewer is opened. snapsvg loaded only when explain plan is executed. This will improve sqleditor initial opening time.

Look 'n' Feel and implementation logic are inspired from
'http://explain.depsez.com'.
It now creates three tabs under the 'Explain' panel when executing a
query using the Explain Analyze/Explain button from the toolbar of the
Query tool.
Graphical
---------
-> Graphical Explain Plan
Analysis
--------
-> Table to show details of the explain plan analyse.
-> Each row represents the statistics per Explain Plan Node
-> It may contains columns like node information, exclusive timing
(time spent for this explain node excluding the child nodes),
inclusive timing, actual rows, plan rows,
rowsx (misestimation between planned vs actual rows), loop.
-> Background color of exclusive, inclusive, rows changes based on
their values.
i.e.
If Percentage of exclusive, and inclusive timings of total query time
is:
> 90 - Red Color
> 50 - Orange (Between Red & Yellow Color)
> 10 - Yellow color
If planner misestimation for the rows is
> 1000 times - Red Color
> 100 times - Orange (Between Red & Yellow Color)
> 10 times - Yellow Color
Also - if actual rows <= planned rows then it shows up arrow, else it
shows down arrow.
Statistics
----------
-> It contains a HTML table for the statistics per Node Type, and
a HTML table for the statistics per table.

workaround rendering speed issues in CodeMirror with very large scripts.
Fixes#4631.
Re-arrange editor options in the Preferences dialogue to tidy things up.
Attached is a tiny but very effective patch to improve the speed of
finding a node using path (used internally).
If you right click or just click on a node, internally the node is
traversed using its path. But currently, it compares with the path of
all the open nodes to find a match.
So if you 1000+ tables and the tables node is open and if you click on
a view, the view path is compared with all the 1000+ tables (and with
any other open nodes above) before arriving to path. You're at bad luck
if you have more open servers above.
Code is changed to check if the path of node to be found starts with the
current node path. If it doesn't match, why bother the children's of
current node.
This change will not show much effect for small data, but it does matter
for large servers.
One more change is to remove unnecessary calls to find node and use the
data available with Main Menu -> Object to enable/disable node context
menu items.
Ensure columns can be created when they are IDENTITY fields with the CYCLE option enabled. Fixes#4496
Ensure purely numeric comments can be saved on new columns. Fixed#4497
