Edit stickers with multiple subclasses

[emiliomarin]

This is what I'm trying to achieve:

I have multiple subclasses of CLStickerTool, right now I can go into a subclass, paste a sticker, accept the changes and then go to another subclass and paster another sticker. I'd like to be able to modify the size or place of the stickers even after I have accepted the changes.

Don't know if someone has found a workaround for this feature, I will work on it and I will post the results, if I get it right.
