One of my favorite plugin in visual studio code is the color highlighting:
Especially if it comes to UI design its a must have, otherwise you will loose the overview at some point because most of the people cant read colors from hex values
it shows the color next to the colorvalue and you can change it directly in codeeditor
it would be great to have this in the B4A or better B4X IDEs. at least the highlighting
In fact I was trying some tools to see the hex color in my code, but failed.
The display in ide will be great, even a popup color on mouse hover on hex color text, if not want op suggested is possible.
