Make "Conditional Formatting Rules Manager" box resizable
As a programmer myself, I know that this is such a simple idea that could be fixed in seconds with no impact on anything else. There's many many suggestions already mentioning it in with other things going back years, but nothing has ever been done about it... maybe the developers don't even bother reading these suggestions any more?
This has been implemented. See https://techcommunity.microsoft.com/t5/excel-blog/resizable-conditional-formatting-dialogs/ba-p/2180229.
It would be nice if suggestions were moderated and identical (or similar) ones were grouped, linked or consolidated (if such functionality exists within UserVoice).
