Quality of life changes

Ability to create connectors without having to join conveior belts, its a pain to build very compact machines in the game.
Ability to upgrade everything that can be upgraded, using tools such as copy and paste.
Bigger limit of trucks, for those who like to assemble modular base this limit is very low in the end game with so many different things to produce, you can introduce some punishment mechanics for exceeding the limit if you want.
Decrease the width that mega trucks have to use to walk on the map, tank trucks couldn't access anything in my base because I made it with 3 square spacing which was what normal trucks used, only after I found out that megas are much wider.
Production / consumption monitoring system such as the dyson sphere program with real-time graphics.

Thought I saw the 1x1 connector thing elsewhere. Good Idea though.
Still have not built the big trucks yet. Would like to get an answer from someone telling me how many tiles I need to plan for the big trucks to get through.
The whole width of the bridge or a bit less?

+1 for being able to place a connector on its own without having to place belts/pipes to create one
