Add an option to open layzgit with a pre-selected file or support filtering files instead of having to search though them

Is your feature request related to a problem? Please describe. I tend to check the diff of the file I'm currently working in quite often and/or sometimes want to check and revert a few changes to the file I'm editing.

Since I mainly work in mono repos, refactoring something or adding features often means a lot of files are changes/updated which makes it a little annoying to either move towards the file I'm currently working on or to search for it (as that still requires quite a lot of keystrokes).

Describe the solution you'd like The most ideal solution would probably be able to open lazygit (which I do from within neovim) with an option that lets me tell layzygit to pre-select a certain file in the tree (or fallback to the top of the tree if the pre-selected file is not in the current tree aka has no changes)

If something like that would be possible it would mean close to zero keystrokes to have a quick look and/or revert changes to the current file I'm working on.

The next best option would be to be able to filter files as the user experience for filtering is somehow much more smooth and natural (for me) compared to search (for how I use it).

Additional context I did notice the text We intend to support filtering for the files view soon in Searching.md, but I couldn't find any related PRs indicating it has been implemented already.
