Thank you very much for this information, Rimu!
I activated this nice option, but at least for me it is a pity that posts that I have opened or voted for also disappear. I want to actively decide for a post to go away. like an e-mail inbox.
But there is a 50%-workaround at least for me; Voyager can do that with it's built-in app specific hide feature.
I use _WiZ Vintage Filament E27, 640 lm _ and WiZ Tunable White & Color (GU10, 345 lm).
Reason: They go quite dark (for cozy evening), have a very low color temperature but still the colors look relatively natural (didn't find this with other models).
The app is good.
