Accounts window UX is not so good
This is probably more of an Instantbird issue, but I feel that the “Accounts” window is way too crowded. Right now, for only one account configured, I have 9 different buttons for one window. I've circled them in red to make them more visible:
Automatic connections warning
I'm not sure why I'm notified that I've disabled automatic connections. I have done nothing to it. It's a default Tor Messenger setting, right? So maybe this warning should simply be disabled. At least it needs to be rephrased.
Also, why is this warning displayed when all my accounts are currently connected?
The fact that it displays a “dismiss” cross so close to the window manager “close” cross is confusing. They look the same and are just blended on the same background. (This is GNOME 3.16.2.)
Account lines
Before negative criticisms, I want to say that I was happy about the interactions to authorize an unknown certificate. The blue underlined action was visible but not saying “you need to hit me at all cost”. We ought to see on more users, but for me it was a good tradeoff.
The “Connect”/“Disconnect” button seems appropriate. The others, not so much. I'm not going to edit the account properties every day once it's working, and I'm certainly not gonig to delete it just like that.
Both options, instead of a button, could probably be in the form of smaller actionable images. A gear wheel or something similar for “Properties” and a garbage bin for “Delete”.
For both of these actions I'm going to look for something to do it, so if there's small and I have to aim, that's fine. “Connect” should be obvious because I should not be required to think too much before talking to my peers.
I don't really understand why the “Sign-in on startup” is here instead of in the “Properties”. Is it really something that I want to change even more often than anything in the “Properties” window?
Delete
When you press delete, there's a “Do not ask next time” checkbox in the confirmation window. I think it's a misfeature and just add clutter. You always want confirmation before loosing contact with people.
New account
Adding a new account is probably not something that I'm going to do everyday. So maybe replacing the button by a smaller “plus sign” would also make the window less cluttered.
Close
Why is there a “Close” button in this window? It seems to be only for the “accounts” window. Why can't user rely on their window manager to do it?
