My ideas: Native features

Ability to use Front in French

This would be especially useful for creating rules. To create rules you have to grab info from messages (subject, sender info etc) and without the ability to create tabs, you have to constantly go back and forth which can be tedius.

Ability to use the Front app while being offline - all major functionality

Include ability to right-click and copy an attachment to paste it somewhere else. Include ability to right-click and copy or drag and drop the email address that is in the "To" or "CC" or "BCC" line into the body of the email. Allow to right-click...

It would be super helpful if you could collapse all subtags under the parent tag on mobile. If you have a lot of tags it takes a lot of scrolling to be able to get through them all to get to a tag group that's listed closer to the bottom

Ability to compose emails with right to left text.

Suggestion to be able to download or print discussions, both individually and mass export
