I would like to ask for a feature to make organizing plugins easier. Adding drag-and-drop functionality would be a game-changing improvement, and the ability to create and delete simple folders freely would be an excellent additional feature.
Edit: +import/export of the folder structure so we could keep it between system reinstallations
Just in case I will drop my observations/propositions for improving the plugin window:
functional drag and drop
marking items with SHIFT/CTRL for mass moving
creating/removing folders instead of groups. meaning allowing to create an empty folder and then moving things inside
when you click “more”, and then click somewhere else - the plugin window collapses back. it should be controlled explicitly by “more/less” button
it should remember folded/expanded folders. for example now if collapse everything and then search for some term, everything expands back
import/export of the folder structure and plugin placeholders inside them
possibility of using keyboard for marking, copy/paste etc
