Chess timer: step 2. Daily increment. 4 polls in one topic!

With the general shift to using a chess timer, a topic on battle management techniques is needed (e.g., pressing "wait" - w, "defend" - d on the keyboard, or what's better). I think I saw in a stream that the troops of a hero standing in a town can be moved to the town with a single action, except for a single unit; I personally move 7 stacks individually. Also, there are probably many other nuances that speed things up, such as exchanging troops between two heroes within a town.
