More levels for the folder tree
Currently, there is a maximum of 3 levels in the folder tree.
I do not know if the expansion of the tree represent technical difficulties or not.
Yet, it would really be helpful to set the limit to 5 maximum.

I use email as an archive and this limitation prevents me from migrating to Proton Mail

This is my number 1 issue at the moment using proton as my primary productivity email. Absolutely critical.

Proton’s closest competitor Tutanota has now added support for unlimited subfolders as part of preparation for their migration feature.

Proton and Tutanota usually are neck to neck when it comes to implementing certain features. Hopefully this triggers Proton to move this up in their prioritization.

I totally agree with Peter below... I don't understand why there is a limit at all. These are just ordered names in some file somewhere (not referring to content) so it takes very little space to have additional folder levels in an account. Very remedial functionality, like this has been around since DOS. Proton privacy is great but it's shocking that this is a "thing"

I'll add some votes to this and link to their support page for more details. I'll also add that I don't see why there should be a limit at all. I don't know of any other email provider that imposes a limit to the levels of folder hierarchy, except for Tutanota which does not yet support subfolders at all. And if you compare it to folders in Windows, there's no nesting limit for the folders as long as the the length of the path doesn't exceed 260 characters.

I've also sent a support request regarding this and got the following reply.
"Please note that ProtonMail supports only up to 3 levels of folder nesting and this cannot be changed at the moment.
However, we will provide your feedback to the appropriate team for further consideration to see if this can be changed in the future."I suspect that the limitation has something to do with the encryption tech being used, but at the same time there are many encryption methods you can use which don't have this limitation, so that might not be the reason.
