You should combine Textra with Contacts and calling app, first. Second, this integration allows to improve several options. From here it goes to the second issue. Now I'm trying to create a blacklist to make group MMS free from answers of my colleagues (like: roger, yes, acknowledged and stupid gif, jokes etc), but keep the vital messages from my boss untouched. Also I need to keep calls and SMS from some of my colleagues unblocked. It requires maitaining two separate blacklists and two apps, complete headache. Also I was surprized how poor blacklist option in Textra is. For example I can't open list of contacts in group MMS and block some contacts separately from the menu of each, or select those I need and block them by group menu option. The only thing I can do from here is to block the entire group conversation as a group, it sucks. The options of blacklist itself go to only "unblock", what a heck? The best Contacts and Messages app I've seen so far the ones in my Asus ZenFone 2 Lazer. But their Messages work only for Asus. It was one blacklist where I could manage each contact separately, either block calls, messages, call+messages. I could blacklist contacts separately from group MMS recipients list.
