When customizing a ribbon, it would be nice to be able to search for a command using text
Instead of having to manually search for the command you want to add the a ribbon, it'd be nice to have a search textbox that would immediately filter and fine the command you were looking for, instead of having to look manually and scroll through all those commands.

Great idea! The list of possible commands is very long. I am usually searching for one to add to the Quick Access toolbar. Would be great if we could have more than one Quick Access toolbar to use according to what we are doing (the days of customizable floating toolbars were great - too bad that was killed for whatever reasons....).
