Very cool, i liek the new light capacity, shadows are working better on my end.
I have one remark tough, i use d1save script for photoshop to save multiple tga maps from one psd with layergroups. And by default it saves with compress (rle) on.
Apparently, toolbag doesn't suport compress (rle) option in tga files, and it's kind of a bother to uncheck that everytime you save. manualy
(because the script is on always)
Oh and i saw the psd support, pretty cool too, but if your file is kinda heavy it's slow to see the result, tga is way better combined with auto reload texture on..
[EDIT] I edited the script so it works now, but it would be kind in to have toolbag support it in a next version, just to avoid that kinda worries.
For those who have the same problem: edit d1vSaveTGA.jsx and add "tgaSaveOptions.rleCompression = false" (without quotes) after the "tgaSaveOptions.alphaChannels = false" line
