I can also say that the cross hotbar 1 is not replaced when using mounts (unless you're doing beast tribe dailies or cannons in df). It also messes with the cycling through the other bars as once you mount, you're stuck with cross hotbar 1 with your abilities that are greyed out and then after hitting the toggle to cycle you are taken to cross hotbar + with mount abilities this time. Seems like a goof somewhere. I tried multiple mounts (drake, goobbue, magitek armor) and the only way to access their abilities is to hit my crossbar toggle and have Use mount hotbar active under Cross in Character Config.

When I try it with hotbar 1 (not cross), my battle abilities on hotbar 1 are overwritten by mount abilities when using the drake and others by hotbar + without toggling/cycling. When I dismount my hotbar 1 is back instantly with my battle abilities. Mount again and mount abilities are instantly back for me to use.
