For #1, if you want to add a custom icon that looks like a chipset or diagram or logic gate. Basically, import a image and use that as opposed to the built in squares. And a toggle for the border.
For labels, I'll have to try out right clicking, but I meant like labelling the visuals of a circuit similar to labelling pins, but putting it on the component so it is visible when other components use it. Similar to how real chipset diagrams might have labels for the i/o or just other custom information, separate from the chips given name
I'll absolutely check out the community version. Sounds great.
