Sub foldersall stay open when I exit

I am not using local folders and I am Synced to gmail. I have 4 email Accounts.
I have sub folders that have subfolders which also have sub folders etc etc.
My problem is that all the ones I have opened stay open even if I shut em client down.
When I reopen em client it makes it very hard to find things.
I am currently having to shut down each sub folder with sub folders and sub folders before I can see all the master folders clearly. It is very time consuming.
I want to open my email accounts and see only the folders for that email account without seeing subfolders and subfolders and subfolders
Can you please help

It is by design so that the state the folders are left in when you close the application will be the same when you start it again.

You can always right-click on any folder and choose Collapse All if you want to close them all.

Or, if you would like to propose a new feature or improvement to change that, or add your vote to an existing request if there is one, you can do so here: https://emclient.sleekplan.app/

Thank You Gary
A right click to collapse all Is definitely going to solve the problem. I may also email a suggestion that it could be a beneficial improvement.
