How do I delete a level that I don’t want anymore? Btw, thank you grazer for helping me.
There is no “delete level” button at the moment (it’s on my list) - for now you can just make it last in the list and ignore it if you don’t want to use it.
While you mention it, delete animation should also be on your list, I have a few with too many frames, so maybe delete frame too, idk, not important tho 
Well mhx air i think grazer should add delete level button,delete animation button and delete frame button! I would really like it. Plus why does grazer have so many things on his list? I guess it will have a lot of people. Thanks grazer!
People suggest stuff very often which cause bugs he has to fix
Oh that is sad. 
But i am glad he can fix them! (if he can)
My own two cents, having used FlowLab for the last few months, I have a definite need for delete options for levels, animations, animation frames (rather than having to draw the eraser over the whole thing).
Making a reduction in frames for an animation right now means having to abandon that animation and create a new animation with the proper mount of frames. Seems like a waste of resources and it gets pretty messy when you’re mistake-prone like me, or just trying to learn the ropes by experimenting, like me. The fear of making a mistake is not something this great program should introduce to a would-be game designer, imho.
Thanks for everything, Grazer!
