Heh. So I made a version of the Tool Bar which toggles between both Photoshop and Paint Tool Sai. EDIT: Bug Fixes. Updated this file Jan 7,2012 2:26 PM PS-SAI-Bar-Version2.zip I looked into having the tool bar automatically know which art program you happen to be running, but that power is apparently one of the big shortcomings of Autohotkey. There are a few very shoddy hack-arounds, but they just looked like too much trouble and too unreliable to bother with, so I just made it a user-flippable switch instead. Just click the logo in the Top Left corner. I've included both an executable and the source .ahk For those who don't have AutoHotKey installed, just unzip and run the "Photoshop-Sai-Bar-1.exe" from within the folder. Thanks again big-time to lblb for making this possible! There's lots of basic code which he brought to the table and which would have taken me forever to work out on my own. -Not to mention that I'd gotten used to my old and not-half-as-good undo button. This new take on an old problem came out of the blue and injected new life, solving the puzzle very tidily indeed! Thanks!!!! This has been fun, and now I've got a super-functional tool which I'll be using on my portable tablet a great deal. Sai and Photoshop compliment each other very nicely, and this on-screen button bar makes them both very easy to sketch with on a keyboardless Tablet.
