1. When creating a post and pasting a picture the dialog pops up that lets you name the picture. If you hit enter to just accept the default name the post gets submitted instead of the image being attached. So the enter key seems to still be focused on the post form and not on the accept button of the little modal that pops up to name the picture. Might be nice to just put the picture name under the uploaded thumbnail so you can go back after uploading and name them all.

2. When tying in an "@" username it seems to be case sensitive and also does not understand backspacing. If you delete a character it seems like the matching function stops working at that point and to get it to work again you have to delete all of the characters you entered and start over. Ideally it would also not be case sensitive.
