I have a Pixel 6 Pro, which is almost as large as a small tablet. I have plenty of space to fit a fully functional tab-bar instead of the tab menu found on the smartphone form factor interface.
In fact, I’ve already tested to ensure it would work by running a Tasker function to alter the DPI on my phone to that of a tablet–forcing Obsidian to use the full tablet interface! While a little on the small side, it works great! (As I mention here: [Feature] Obsidian Mobile: Allow toggling between phone and tablet interfaces - #7 by Ruq, many phones could use the tablet interface to boot)
Thanks.
