it'd be really useful to be able to toggle the level of the scanning in a global way, for exploring the super range is super useful but being able to toggle the wider scans and maximum range of always visible would reduce day to day lag without having to uninstall the mod and replace all the radar in my base

Interesting idea. I hadn't considered this but toggle-able range (downgrading) is possible. Maybe I'll explore this.

I thought one way to do it in game might be a science that researching turns off another science pack and vice versa Research expanded radar unlocks research reduced radar which toggles the expanded radar research off so you can research expanded radar again which when research resets reduced... you get the point XD

Perhaps the surveillance centres could offer a slider or toggle of some sort to adjust the scan range and speed of radars on demand? I do find that loading as many chunks as I am now creates a decent amount of lag, though it can occasionally be useful.

A this would be useful. I installed this mod during endgame and had hundreds of radars already. It was causing 200ms or so microstutters every few seconds. I disabled the mod, it deleted all my radars, then I reneabled and added back just a few that I needed and it is okay now.

Until this feature gets added, you can use this console command to undo all radar research. Then you'll have to research 1 level for all the radars to update.
