Please create a version that hides those 2 folders:
-Junk folder
-templates folder

Rated 5 out of 5 stars

In 115.2.2, "Local folders" still appears with or without
your addon, including "Outbox", what would
be nice is getting rid of "Local folders" & have
"outbox" for all accounts in one icon under
"Inbox"

& a plus would
be nice:

Hiding:
-Junk folder
-Archive folder
-Templates folder (& disabling it)

It sadly stopped working in the latest v91.5.1

This review is for a previous version of the add-on (2.1.0). 

I'm also using 91.5.1 (Win10Pro) and the Add-on is working without problems. You can contact me at k-l-p@gmx.de and we can try to find the cause of the issue.

An option to hide "any" blue accounts would be nice too. I use the unified version of folders view,
so every emails from any accounts arrive in the "black iconed" inbox.

This review is for a previous version of the add-on (1.0.1).
