I notice that if I put on the region-override to restrict push, the "restrict push" checkbox is greyed out in about land->options.
I notice that this is not the case if I use the region override to :
* disable fly for the region.
* exclude residents from the region based on payment status.
* disable terraform for everyone in the region.
* enable damage for the whole region.
This is a minor UI inconsistency. It's not urgent or anything.
In fact I'm almost hesitant to bring it up at all because... well... the region override for push option apparently had a bug whereby turning it on had a 10% chance of wiping out all objects in the region :/
If at some possible future date you have fixed all the bugs in SL, and have implemented all the major features people are asking for... then maybe at that future date you could consider it?
