This is really a Nice app to work with. I also like the customisability of the UI. However, I feel that there should be a chance to sync with the local SMS app of Android. If I delete any message in Textra, the local sms app of android also should be synced. So that I need not delete it in 2 places. One Textra & Two the regular SMS app of Android.

Please look into this & try to fix the sync issue
