there was a "unit queue patch" from a long time ago, but it no longer works and no one with know-how has wanted to fix it on account of how drastically it changes the game, unfortunately. however, there is a new event in the latest version of the editor which forcefully clicks something on the player's sidebar for him. making that repeat and implementing a system for it would require a workaround, but it is possible to "queue" things that way now. the event should be number 100, here:
I've been thinking; why not implement Unit Queuing as a game option? Kind of like how you can enable Crates or Worms? That way the people that want it can have it while the people who don't want it can just ignore selecting that option. Don't know how to implement is for the main campaign or any pre-exisiting campaign but that can be future goal.
An actual bug I found was in the WoL missions, especially in Mission 2 for the Sardaukar: sometimes the "Missile Launch Detected" line might get switched with another random line or sound. I've had both gunfire and "the ordos are coming closer!" play when selecting the target for the nuke.
Non-code-based suggestions: Would it be possible to give the Smugglers a different colored tank and structures? I get they're Not Ordos but if you have them, Mercenaries and Ordos all on the same map its kind of a mess. The main issue I can see would be if a re-color was applied then it would affect anyone using an Ordos Tank thus making the change to begin with useless.
Then there's the Mercenary Tank. I think, haven't tried it yet, that this one suggestion could be done via the new map editor. Anyways I was thinking that it would make more sense for the Merc's to have the Atreides Tank. Both from a statistical perspective, since its the all-rounder combat tank, and from a visual perspective since the Merc Heavy Factory has that sloped roof...
