Improve jump-to-file ergonomics

[Johni0702]

A nice jump-to-different-version-of-this-file action is something I've been wanting for a long while, so I'm quite happy that this plugin provides one (PreprocessorFileJumpAction). Unfortunately I find it quite lacking in ergonomics, especially trying to use it keyboard-only. So much so that I end up using the standard IntelliJ Search Everywhere most of the time anyway.
Here's a bunch of improvements I'd love to see:

• The filter/search bar should be selected by default
• Pressing Enter while in the search bar should directly jump to the selected (by default first/top-most) result
• One should be able to select between results with down/up arrow #22
• Fuzzy matching

In my ideal scenario I could jump to the 1.21.7-fabric version by simply typing <hotkey>217<enter>, and to 1.21.7-forge by typing <hotkey>217<down><enter>.
