Enhanced Customization
I'm coming to Textra as a longtime user of GoSMS. A major update to Go (version 6 I believe) removed most of the features that made me choose it in the first place. Luckily, my apps don't auto-update, and I've lived with an old build of the app for quite some time.
I love that Textra has many of the customization options I like while also being fresh and fast. However, I think it would be incredible to see the following functionality included:
-Option for customized vibration patterns with numbers (ms on, ms off) instead of presses (although the press idea is neat!)
-Custom LED colors (using RGB values)
-A single place to view, create, and manage scheduled messages
-Persistent message counters
-Open menu when tapping phone's menu button (Does not work at least on my Galaxy S4, and I understand many new devices do not have such a button)
-iOS emoji (Perhaps there is a licensing/copyright issue? Changelog indicates that this used to be available)
