Exclude window borders
An option to exclude the titlebar and window borders from a window capture would be very helpful for me when screenshotting software running in DOSbox or other virtual machines. I can do this after the fact, but it's very tedious to crop to the exact pixel-perfect dimensions in an editor, especially when I'm rapidly capturing many images in a row.
If automatic exclusion of the borders is impossible (e.g. because Windows doesn't provide APIs to determine their geometry) an extra capture mode, with its own keyboard shortcut, that applies a predetermined crop factor to each border would also be helpful. I attached a mockup to illustrate how a user would enter this preset.
Thank you for your consideration and your work on this excellent tool!
