It would be nice if we could somehow set our starting parameters, so when we create bins, we don't have to switch everything.

Personally, I always set the bases to be very simple (no screw holes, no magnet holes), and usually would like to go for 3x3 instead of 2x2. This means I need to change those properties for each bin.
The size isn't as important, since I do work on different sizes, but I usually would like to have same base for all the bins in the project.
