Ctrl+F should highlight all matches, and in realtime

[teo1978]

Again, this is basic functionality of the Find tool that one usually finds in EVERY text editor I can think of, but is missing in Mergely.

When you hit Ctrl+F and start typing in the search box, it should behave as follows:

• update the results in real time as you type, without waiting for the user to hit Enter or the "next" button
• highlight ALL matches, and the selected one with a different highlight color (as opposed to what it currently does, which is it only highlights the next one)

this would be an enhancement for https://editor.mergely.com, not the mergely library
