The link given by Rosletyne is in fact interactive, but whether the codebase is shared or not, I do not see a reason why such a valuable and hugely necessary addition would be considerably complex to incorporate. We are talking, on the most fundamental scale, simply grouping units together by health.. we aren't talking about anything on the scale that perhaps GvG took to program. Heck, I imagine these special events are more complicated to program than the suggestion under discussion here.
It would be nice if someone from FoE could comment on whether this is being seriously looked in to, or at the very least, acknowledge it as a consideration.
While the link is interactive it's still an isolated component. For example the attached troops that we see in it aren't actually attached to anything and the defending troops button doesn't work like it does in the game. It's good work and a very effective visual, however it'd still need work to actually incorporate it into the coding behind units as they currently exist.
Now I'm not saying "Inno won't consider it because it's work" but changing the army management in this way would take a lot of time (Starzaan already mentioned it'd need the coding behind units to be changed up). This means we most likely aren't going to see such a change for a while unless Inno decides to push other things back. It'd be a handy thing to improve troop management but is probably a more time consuming task than some would think (very hard to judge these things without knowing the actual code).
Hopefully we can get some feedback via Starzaan early in this new year about if they will consider the suggested changes here. If not there is at least 1 other suggestion in the ideas section that might help. One thing for sure is that army management could do with something more to make it better for managing large numbers of troops.
