Added rounding of the number of objects in clusters greater than 1000 (each thousand objects are displayed as - 1k, 2k ... 5k, etc.).
Fixed cluster visibility setting for layer by zoom (previously, clusters would not disappear when visibility was limited)
Added adjustment of zoom options of the displayed map (underlay) proportional to zooms. Performed in the settings: section "Map Setup", "Tiles scale factor" (default - 1.0, range 0.5-5.0)
Added reducing/increasing the map zoom by buttons of smartphone/tablet audio level setting. Settings: section "Map Settings", "Zooming with +/- keys", (by default the mode is enabled)
The item "Show map zoom" has been excluded from the settings (left always enabled by default). Object creation/editing menu was changed (edit buttons: "Edit properties", "Use map rotation" - moved for quick access to the object creation menu (the buttons were moved from the neighbouring menu to reduce the time of work with a graphical object).
