I was doing a 2d animation and all was fine till i maybe hit a hotkey or pressed a wrong button. I used to be able to see my layers on the bottom left in my timeline (the default 2d-animation settings) but now theyre gone. I have a lot of progress sunk into this file so I'd be a shame if I had to start over. Please let me know how to fix this, My guess is that its probably a hotkey I pressed but your guess is probably better than mine. Thank you in advance!
