Add ability to sort Repo by alphabetically order

I have over 150 different apps, I use SourceTree for these, my problem is I see all my 150 app bookmarks in the left column of source tree but they aren't sorted alphabetically, also I'm able to add duplicate entries.

I'd like it to remove duplicates or at least warn that I'm adding the same folder again.

I'd like to be able to order by Apps alphabetically, then I can easily find the app I'm after, also a search would be good, but I'd consider my number one request to be a simply option to sort alphabetically.

Thank you.
