The handles on modules in the procedural editors are significantly too small. This makes it really hard to connect one handle to another. I'm not the only one to voice this opinion (other's have on the forums) and it's been an issue since the beginning of the procedural editors, as I understand it.
The handles, or at least the clickable area for each, need to be significantly bigger. I recommend 30% to 50% bigger.
A lot of us will breath a sigh of relief to be able to connect one handle to another by clicking and dragging only once, instead of over and over again. This issue doesn't limit AoI's functionality but it is *really* annoying to deal with. Fixing this will save users a lot of time that is currently wasted re-clicking-and-dragging.
