Considering the alternate movement methods as well as mods (such as 40k) that use energy for special actions, it would be great if the path preview arrows could also display remaining energy next to TU. This should prevent that a player has to calculate and/or save/load to get the unit as far as possible while also having sufficient energy left to do a special action.
Attached is a small mockup how it could look. For reference bottom is Index 48 (a2e386) for remaining TUs and index 16 (ffd300) for remaining Energy. Of course any other color works too.
