I was searching for a way to mimic what I used to do with Outlook where I have multiple e-mail accounts connected to a single .pst file that I "took with me" from home to work. This works pretty well. I too would like to see the ability to create a button for each profile, then it would be perfect.
One thing that I miss from Outlook is that when you click "send/receive" or hit F9, it only looks for mail from accounts that are checked to do so. In TB, even if you have unchecked all the boxes in the server settings, if you click "get mail" it gets them for every account.
This is where the "get selected mails" works so nicely, but let's say I'm trying to change the profile and don't quite click on the down arrow on the edge of the button and click the button instead, I just checked all my mail when I didn't want to.
Let's say I log into my home PC remotely from work, and I need to check messages that stay on that PC and that PC only. I don't want to check messages on accounts that I "carry" with me. If I click the wrong button, I will do exactly that.
Having a completely separate button that could be connected to a specific profile would solve my particular set of issue better.
This review is for a previous version of the add-on (0.6.0).
