2) Image tab:
In the back-end image tab, when we set the max widht and height it allows user to upload rectangular images and there is no way to set to upload for example only squared images, like 100x100 px and so on. So, it would be interesting to have the option to inform user that just get to upload 100x100 image or a system to upload the user image and he can crop it in the set size. Well something like that.
3) Coming soon...
