To add a window(s) to the list just click 'Add...' then click on the windows titlebar or you can click 'Add all windows' to add the lot! You can also pass the string '-tidy' as a program parameter to just move and resize all previously captured windows or the program parameter '-record' to record new or update exisisting windows without opening the GUI. Click the window button (in the middle of the arrows) to resize the windows to the captured settings too. Click the screenshot to download.

of course, critisism and/or improvements are most welcome.
