This looks like a good start!

I've been looking for similar software as well. It's a challenge to categorize and stock parts, probably more so than a simple spreadsheet or a first try at inventory management can handle. How to categorize a part may be very different throughout different use cases - Whether you need a 555, any old adjustable LDO, a low-leakage diode, or a 1k resistor makes for a wide variety of storage mechanisms. In addition, it's probably good to keep a few sources and manufacturers available for many of the parts...

Will have to give that a try!

Because the OP is concerned about managing information, not the physical objects, and because most plastic compartments are not ESD safe, and the ones that are conductive (designed for IC storage) may be prohibitively expensive.
