### 4/5 — Cool app with great potential, but…

*2026-07-30, version 2.7.6*

I’ve had this app for my LED car display for a few years now, and really enjoy it, and while there have been some welcome updates, it still has some bugs.

 The MOST annoying of these bugs is the way it disconnects ANY audio playing on my phones through my car stereo as soon as I open the app. 😬.

Can the developers PLEASE fix this? Pretty please? 🙏

PS: I’d also like to be able to DELETE animations and images I’ll never use - like all the American-themed junk, and the ride-share icons and animations. 
And finally I’d like to be able to rearrange them in preferred order. 😉
