Wow, this is great!
Used the Locus 4 alpha version today, and those are the things that came to my mind:
- GPS in Map center button. Crosshair is brown when searching for signal. Crosshair turns green if GPS is locked. Long tap brings options to hold map center, turn off gps, go to GPS/compass screen. Would make all the location functions/indication in one place and accessible.
- Integrate Map center button into Bottom panel (lower it), OR, even better, move it outside the panel and to the left/right (a la gmaps). Too much screen space is wasted now and is akward to use. Also when adding more than 4 icons to the bottom panel the fifth one appears outside the panel and under the location button, which is not nice.
- Slide up bottom pannel to access menu (similar to gmaps, app drawer in android). Intuitive.

- Right pannel realized in a way of small round floating buttons, the same as Map content button, with each function in its separate button. Would make the interface much more elegant, modular, light, tapable and consistent with the circular theme. Will add possibility to elegantly add functions to the left too, on top of the Map content button. Will add possibility to make each function a button with different states (on/off/color/etc), would be amazing for the track rec button, for example (make it red while rec).
- Make Map content button blue, it's a Locus design trade mark in a way

, looks nice and everyone is used to ıt (i guess).
- Opacity (opaque) slider for the Overlays layer directly on the main map screen. İndispensable when overlaying satellite maps, comparing different maps, or anything layer wise, really. Currently, when adjusting this setting the Map content and overlays menus are always in the way, so the map is not even visible.
- possibility to add a point directly from an address popup screen/menu (long tap on any place on the map).
I am really liking this design language so far! Will test more.
All the best to you Locus Dream Team
