amazing suite of apps; essentially gives me a lot of the customizable options I had Nova Launcher pro for. One feature I'd like to see on NotiStar or whichever application is relevant is the ability to see my notification history from the dropdown menu My last phone was a Pixel and when I pulled down the status bar and it said "no notifications" I just clicked on the blank space and it took me directly to the history. 5 stars, it's really smart to have the stock UI and then these as optional.

love this app! easy to use (after a little learning) and my screen is sooo cute now! only thing is i wish we could edit or change the icon app names, and i wish i could add more than 20 stickers at a time. (im veryyy decorative.)

I have not played with all the options, my favorite is NavStar... but my problem is that the screen shots show options that do not match the screen in the app itself... Also, most of the time my Nav bar is white on black or white on grey, but sometimes it is white on white or black on black. I don't know why, & I don't know how to fix it.

AOD notification icons are way too small on the Zfold 7, on both displays, to the point of barely being readable. This is such an obvious flaw. Please make them larger or let us choose how big they are! Update1: in addition, there is no separate control for AOD brightness. To make the AOD suitably bright, you have to increase the display brightness so much that the display is too bright.
