Thunderbird for Android Community Forum

I've recently downloaded thunderbird as I've been sick of outlook on Android for a long time. In general, I do prefer it a fair bit over outlook, however, the search function doesn't work at all.

Are there any workarounds for this or is it a bug that the Devs are in the process of sorting. I use the search function a lot with my emails, currently it's just not possible on Thunderbird at the moment.

I'd expect there to be some way of "only showing unread messages" (just like there is in the Desktop version of Thunderbird), but it doesn't seem to be there?

"Mark as read" is there but a bit well-hidden (swipe left either on an individual message or on a thread) but "View only unread" seems to be missing?

This is the case with both a personal Gmail account and a self-hosted IMAP account. In case it's relevant in the first case there is a "[Gmail]/Starred" subfolder but no "[Gmail]/Unread" one; in the second case the only subfolders are ones I have created myself.
