I have a Moto X and really like the active notification feature, but the Textra notification icon looks pretty bad when it pops up. (I'm using the white icon, which is closest to the stock messaging icon.) Most other apps have white vector images for their notification icons that display very nicely on the Moto X, and I think this would be a great addition to Textra.
You devs are doing a great job here. Keep up the good work!
