<!-- Code Style:
|
||
|
||
Do not use any JavaScript or CSS frameworks or preprocessors.
|
||
This HTML page should not require any build systems (node.js, npm, gulp, etc.)
|
||
This HTML page should not be minified, instead it should be reasonably minimalistic by itself.
|
||
This HTML page should not load any external resources
|
||
(CSS and JavaScript must be embedded directly to the page. No external fonts or images should be loaded).
|
||
This UI should look as lightweight, clean and fast as possible.
|
||
All UI elements must be aligned in pixel-perfect way.
|
||
There should not be any animations.
|
||
No unexpected changes in positions of elements while the page is loading.
|
||
Navigation by keyboard should work.
|
||
64-bit numbers must display correctly.
|
||
|
||
-->
|
||
|
||
<!-- Development Roadmap:
|
||
|
||
1. Support readonly servers.
|
||
Check if readonly = 1 (with SELECT FROM system.settings) to avoid sending settings. It can be done once on address/credentials change.
|
||
It can be done in background, e.g. wait 100 ms after address/credentials change and do the check.
|
||
Also it can provide visual indication that credentials are correct.
