Custom virtual folders

Hi. I’m trying to migrate from the!bat.
In TB! I have several virtual folders to organize the inbox of many accounts, like this example


I can’t replicate this with eM.
I’ve tried with local folders copying the message, but the read status doesn’t replicate between folders (inbox and virtual). I want to keep all the messages in the inbox, not moved, so i could access them with a browser when I’m not with my PC.
The search folder seems to work like I need, but i can’t create subfolders, to organize them. Is there a way to do it?
I want this done at the client side, not server side, because the filter must search in several accounts and I don’t want to replicate the folders in all accounts.
Thank you .

Unfortunately you can’t have folder trees in Search folders, and they won’t show unread counts either. Sorry.
