The app does not remember the "Sort by ping" state of Countries and Cities lists. When another category tab is selected or a favorite is selected, or an item in the list is selected for connection, the list reverts back to alphabetical sort.
It is VERY difficult to mark a country or a city as favorite by the small star on the right side of the row, especially on small screen devices. 9 out of 10 tries initiates VPN connection, instead to mark or unmark it as favorite.
Please remove the slow animations (at startup, etc.) - we need a fast app, not a flashy app.
