Bring this feature back, it's a godsend and it's not in 99.3. The last build i saw it in was 98.9. It worked great, and was a main feature for creating new levels quickly and efficiently.
I didn't realise it had gone! I think Rich should look into that, since he re-did the project bar in 0.9.

It was over worked and took a break. Should be back on duty soon.
