Plugin for CudaText.
It was heavily updated by @Shovel.
Before: plugin could show icons for tab-titles from fixed icon-theme like VScode_16x16.
Now: plugin also can attach custom icons to tab-titles.
It now puts menu item "Set tab icon..." to the tab's context menu,
and that shows menu with several pre-installed icons. Icons are taken from GNOME Adwaita theme.
You can put your custom icon files for plugin, see plugin's readme.txt.
Plugin also allows to auto-collapse "Pinned" tabs (pinned tabs appeared in CudaText 1.130+).
If you set some custom icon for the tab before 'pinning' it.
