confusing UI in the osX version with multiple accounts.

Using 1.10.15 - OSX

When having multiple accounts they are listed left in the window. One account is always on top. When switching to an other account that one is placed under the first account causing all icons to slide down.
This is confusing since it is not very clear in which account a new toot is made. Normally I expect the top listed account to be the active one and not the lowest in the list above the tool icons.
This could be a matter of taste but mine says that the icons should remain on their position and not slide down. Maybe it is clearer to switch from accounts using a popup menu where the current account is identified and the alternative accounts are listed.
Having the ability to arrange the accounts in a specified order would be nice.
The option to rotate through the accounts using a hotkey would be nice. (Command - arrow left/right?)

No file, test, or entry point is named. First clarify which account-switching behavior is wanted, since the issue proposes fixed icon positions, a popup menu, account ordering, and keyboard shortcuts; done would require an agreed scope and verified account switching on macOS.
