The one thing bopimo creator page is missing is grouping parts together the bopimo build system is intuitive itself, but this would save so much time and make level production so much easy
Building assets for inside levels is an atrocious task and having to select each individual piece when individual parts are sometimes inside each other is annoying (I know about the ctrl lasso select)
Let's pose a situation you have a 30-block detailed table you like the table, but you don't like the angle it's at you think the table would look better on a different angle

you can't just select all and rotate this way it adjusts all the angles to the part you are rotating so you have to rebuild the table again at this set angle you want the table to face
and resizing is a similar process

Grouping you can just rotate the whole without doing all of that and resizing only scales up the model and you can duplicate them wherever at whatever angle is needed

2ed idea - locking an object makes it no longer selectable so you don't have to worry about accidently auto selecting something when using the ctrl lasso

3rd idea - An improvement to lasso - select all lasso additional lasso by holding CTRL shift and selecting is that it picks up every object in the area of affect not just the visual hitboxes how the normal lasso works
