I’m in the newest Windows version of Pencil and, unless I have no idea how to use this software, I am unable to immediately undo the act of deleting a frame.
Now, sometimes things get a little buggy if I scribble in a frame, delete that frame, and then immediately hit undo. The program will undo the last line I drew, and in the process bring the deleted frame back from the dead, but then it gets confused and seems to overwrite the frame before it instead. So, maybe this bug is just for me, but it makes the lack of an undo-delete feature doubly bad because if you want to bring back your old frame, you’re deleting a different one instead.
I hope I’m not the only one who accidentally hits the delete frame button sometimes and then screams as I destroyed some of my work, so it’d be nice to make this a feature some time in the near future.
