Issues and questions about preview-tabbed + alacritty + bspwm

[TheUtopian]

Recently I've tried preview-tabbed, I really like how it works but I've encountered some annoying issues. I decided to write it here because some of them are not nnn issues and I wanted to write them in one post instead of creating several issue requests, but if you think I should create issue request, I can.

1. When I watch text files or folders with preview-tabbed it doesn't close alacritty properly so sockets created by alacritty aren't removed. I've tried to use one instance of alacritty for all windows like alacritty msg create-window but it doesn't work with --embed attribute.

2. [Partially fixed] When I switch files to watch, nnn takes focus for a second and I cannot switch to another window or change workspace (because bspwm returns me back to the workspace that is selected), It also happens when I want to use filter, I cannot write more then one character. I don't know how I can show it with screenshots unfortunately.
(I fixed focus issue by removing this line from preivew-tabbed: timeout "$XDOTOOL_TIMEOUT" xdotool behave "$XID" focus windowactivate "$MAINWINDOW" &, but I still cannot use filter)

3. When I want to preview text files preview-tabbed opens them (with nuke) in non read-only mode and I cannot open selected file because they're already opened in preview editor. (I use neovim).

4. [SOLVED] tabbed shows windows with title how can I get rid of it?
