This one tries as good as it can to figure out what tools in your selection meant to be connected and connects them. Works for many unconnected tools.
The priorities in following order:
Creators are Male
Tools that already have Inputs are Male
If there are no Female Tools use the ones with secondary inputs (not masks) as Females
I recommend to bind this to ALT-C (for connect).
This is again a rough sketch. Disclaimer: It's not as smart as it claims to be! ;p
Speedy happy testing.
