AT, I hope you don't get too mad about this, but... I have the first 1.74 bug report.
Your new 1 kt Mini Supply Storage component is a good idea - it's always nice to fill those extra kt's with something useful. But you made it the same family as the regular Supply Storage components - so when I go to upgrade a design, all my 10 kt supply components are replaced with the 1 kt model.
Just a heads-up...
