Your first suggestion could raise a large amount of issues, such as not having enough recon drones, which players gets priority if there are not enough recon drones, players wanting more buttons like this (But for other troops), and the UI change to accommodate the new feature.
Your second suggestion could greatly complicate things if each player had their own individual colours/details; the storage Plarium needs for each individual possibility would be large, to say the least.
Your third suggestion is basically a modified version of Joint Attacks, which should be a clan-specific feature.
