Duplicate names: Currently it is possible to name and upload RA styles with the same name as a previously added style which causes confusion. An error message should be displayed when trying to do this.
Removing styles: Removing a style show the message "Are you sure you want to remove this CSS file?" regardless of the styles content (CSS / logo or both). Message should be changed to "Are you sure you want to remove this style?"
Size limit: There's a size limit for uploading files. However, no warning is displayed while exceeding this limit and the upload fails.
