I think it will be very beneficial for players to have the ability to create reminders in custom time intervals. Like, for example, you get to create a reminder where every 2 minutes you will get a message to "build energy" or in every 10 minutes you get a message to "scout base".
The reminder could appear in the chat (visible only to the player) in a distinct coloured text along with some kind of notification sound. That's just an idea though, there might be better ways to implement it.
