Units can't be hidden to the other side. My take is it creates too much overhead for little effort, particularly in PBEM games. Should very be need to add this feature, let me know.

When unit isn't at its full strength it is marked with letter "R".

Some units can be assigned to other formation. You would also use ^L to denote units designation to see at first glance which units changed their original echelons.

Units can be deleted from the board with ^X--to prevent mishaps this hotkey only works on maps other than the main map.

In scenarios victory point locations are marked with red outline. You may select each outline by clicking on it while holding left Meta (Alt on PCs) key. You can then flip it to US side (with ^F hotkey). In module there is inventory button automatically summing up VP from locations currently held by US.

VP outlines are visible by default. Click on "Show VP locations" in the menu bar to hide them. Another click makes them visible again.

There is marker palette. You would use blank marker to denote base odds, DRMs and combat results. In case of results you may want to use "Rx / By" notation, where "Rx" stands for red x result, "By" for black y, so for example "B0 / R2" means 0 losses for attacker, no check required, two losess for defender, efficiency check required. Use ^L to change label of blank marker.
