Here is what I have on my tablet:
I have many remarks about it:
- Two about buttons on the map: one at the top left (with our custome made one) and one at the bottom right (comes from the source I guess). One is enough, we should just keep ours.
- Positioning of our About button top-left is not optimal because 99% of users don't need it, but this is still the first thing they always deal with. We shoukd move it at the bottom, probably bottom left (bottom right would be acceptable as well).
- Question mark symbol is for help usually, most of users might end up clicking on it for wrong reason. I believe the circled I (like on bottom right is better). But this logo is too small for me on my tablet, I almost always fail to click on it. I believe a full transparent button "about" would be better: bigger, clearer and visually not so impacting (because of background transparency).
