It would be nice if there is some sort of dedicated numeric hotkey for dozers if you can implement it in that dozer subtab.
This is just an example, lets say I build 5 dozers, upon appearing on the field they are automatically assigned with a number. You can now instantly quickview them by pressing say D+1 for Dozer 1, D+2 for Dozer 2 etc.
Now say dozer 3 is killed and you built 2 more dozers making it a total of 6 dozers on the field. The first dozer would take dozer id #3 and the second one would become #6 respectively. You can reassign the dozer id if you wish, but I won't elaborate on that part yet. I just want to say that option is open in case someone asks about it.
My only slight problem with the auto dozer number key is that if we adapt Starcraft like dozers (more dozer = faster building construction) then my idea above might not work for that style. We can perhaps do a click-drag selectbox the dozers and manually assign a dozer key for them like how you would normally create a unit group. That also might be able to address the 10+ dozer problem too ^^
