Filter in Lists

[Xanadul]

Description

As an alternative to the incremental search in lists (ie. different keybind), I'd like being able to filter a list.
Eg. suppose I'm on the Directories tab with many entries and hit the filter keybind:

• User inputs a filter string, similar to the incremental search
  • Each keystroke: Entries not matching the filter string dissapear from the list
• Confirmation with return lets me continue to navigate the Directories
• Subdirectories aren't filtered
  This should work in every list tab.

Ideally the filter could be further configured: Fuzzy/Levenstein matching+sorting or only exact matches.

Additionally, the incremental search should use the prompt "[SEARCH]:", while filtering prompts "[FILTER]:"

Proposed solution

The developers of Inori mentioned that they implemented Fuzzy filtering/sorting with the nucleo crate.
