I found that I can disable all default tips by disabling "tips" namespace via configuration
but how can I add new ones? it also disables tips that I added,
how can I create my own namespace of tips
is there any way to write down tips in only one file easily?

This is described in the wiki. The namespace is taken from the folder structure of your resource pack. If the file is assets/namespace_here/tips/your_tip.json the ID would be namespace_here:your_tip. If the file was assets/mycoolpack/tips/tip_one.json the ID would be mycoolpack:tip_one.

thank you alot, does mod support adding or disabling tips from game? if not I think this should be the target functionality, adding tips from ingame ui would be very helpful
