Not a developer help here, but if you want to know, I think I can help you some:
Ad 1 - Skipping it.
Ad 2 - Unfortunately not. You can go the other way round, double-click an object in preview window and use the "find node in the network view" option. Something along these lines.
Ad 3 - Not sure what Quad-views are, and whether they exist in TG. So I'll skip this question.
Ad 4 - Not really... as they would probably need to be updated each time you move a camera to have any SA-relevance. Measurment tool is the only method.
And continued...
Ad 5 - No (next release of TG4 maybe?).
Ad 6 - You can. But it might be hard to "grasp" it because, for some strange reason, you need to grab it slightly underneath the displayed arrow-box. Better way - first, select an object in the perspective view and then switch to top view. Whenever an arrow lights up, you can move the object along that axis.
If you still cannot move an object make sure you don't edit some population. If "Edit instances" option is on, you are unable to select or move anything that does not belong to that population.
Ad 7 - Skipping it also.
Ad 8 - Good idea. Especially that it is pretty useless...
Ad 9 - Please explain what do you mean by "not standing correctly" as it may have a few root (pun, pun) causes to it. If, for example, you populate a slope, you need to bend it IAW a slope's angle. Alternatively, decrease object spacing, and make your grass pop tighter and denser. Wide populations and objects often fare poorly on slopes due to size.
