I've been out here for 3 months but this is my first post. I hope the Crackberry pics download w/o issue. I too leave the tools in their original cases or toss all like tools in a tool bag (i.e. mouse, orbital, 1/4 sheet and 1/2 sheet sanders). I try and add tools, attachments and accessories into these cases as well. Now for my contribution:
My favorite or mostly used tools get a dedicated bag and I add additional things in with them to become a grab and go bag. they are on a shelf in front of the plastic cases right at face/chest height:
The next two pics shows the Worm drive inside and out of his bag.

Then the Sawzall gets a bag.

There's a hammer drill bag that houses all my hole saws, fostner bits, concrete bits, tapcon set as well as a set of drill bits and blade bits.

Lastly and most used is my Makita bit driver. The accessories have grown to do anything I need to do with a cordless. I'll post a couple pictures to describe.
