As there is no "bulk update" from lists, the user must thread one by one down the list. The changes can't be seen without refreshing the list, and to add insult to injury

the blue positioning highlight disappears when you come back to the list. Imagine 50 light poles, in a row, in the list. Now, was it the fifth or the sixth one I last updated?
Oh, and while on the subject, is there any possibility of being able to actually change the object itself while editing? I've got the position right, the direction is correct, I've got the scale right, but I've just found a better fit. Oh, well, delete this one and start again! I think that being able to change individual scenery objects either individually or in bulk would be an excellent additional feature.
These things come in waves, don't they? I was working with trees the other day, and thought how good it would be if I could set up a small copse of trees, then select them as a group to move or copy them elsewhere.
I'm going to limit myself to three harebrained schemes for today - otherwise I might just wear out my welcome.
BTW, these are all small incremental changes - not earth shattering, and the tool is excellent as it is - like most fanatics, I just want more!
