I assume it would be relatively simple from a coding perspective so ill ask in hope that a dev add it to the binary.
The goal would be to give power for lua script to delay or prevent sector from unloading if needed (this way specific sector could be kept loaded permanently if the server owner desires it).
The way i see it, there should be a lastactivity time variable in the sector that once "now - lastactivity > sectorUpdateTimeLimit" unload the sector. A way for a lua function to set lastactivity to now would be good enough.
For all i know there may already be a function accessible from lua that happens to do it as a side-effect, but i haven't found any xD. I understand that keeping a ton of sectors loaded is bad, but the ability to designate a few specific sectors to remain open should be manageable (and in the host control so its on them anyway).
Proper Out of sector idle would be ideal, but that's not likely to happen anytime soon (out of sector factory is great, but it doesnt cover mining ship, pirate attacks etc).
My specific use case would be for a server that only me and a friend play on, wed like our mining ships and patrol to keep sector open without having the side effect of keeping dozens / hundreds of sector open by upping the sectorUpdateTimeLimit to a crazy number.
