Flip Feature (the yellow square) I mean, It's in the name, so it should be added. (lol jk) But jokes aside, This would allow the character/object your animating, Turn around! It'd make having a character look in another direction, SO much easier, you'd just click the drawing space in the layer with the thing you want to Flip, and it goes from this: (l_) to this: (_l) in the span of 1 second without having to redraw the character! For a placement on the tools... let's see... how about next to the size tool? They look cozy together! How it could look: https://aggie.io/api/share/a712731d51.png

Quick Collab Feature (the 2 gray people): Yes, I know that You can Collab pretty easily of ufile.io and stuff, but I want a Built-in Collab Feature, Here's how it would work, next to the, "Latest Comments" icon on the top menu, a new icon would appear much like the one I made, click it, and you'll be brought to a menu that lets you Create, or Search for users collab files, For create, click on a button and you'll be brought to a menu that lets you choose one of your animations to become a collab file, so when you type your username into the search box, you can see that your animation is on there! Speaking of which... The Search feature allows you to type in a username of someone that's doing a collab, and find that user's collab files! Click on the animation you want to use, FlipAnim will ask, "Do you want to download this Animation?" By clicking yes, you download it! Quick and simple!
