Plug in style tab for python scripts... custom icons?

is there a vanilla way to store custom python script elements in a tab and add custom icons to them? I find myself more and more scripting elements and I’m constantly having to search around the canvas to copy and paste what I need or search for the file on disk. I would love to be able to just add them to a tab at the top like the way plugin elements appear and drag and drop in a similar way. and have them come up in the fuzzy finder after double click…

not sure if this is a feature request post or if the functionality exists but isn’t obvious.

Yes you can by choose …SDK mode and than compile and choose your own icon and where you want put your component, or you can create cluster and save it as ghcluster
