I have a couple of mods on ksp and I want more but cant find any good ones that don't require a mod manager. I tried to install Ckan but my windows defender marked it as potentially harmful and even though tons of people use it I'm still a bit nervous to download it So I'm looking for either an easy to use mod manager or some basic mods like some better graphics and SOI boundaries being displayed. Thanks! Ediit: Just downloaded Ckan and wish I downloaded sooner, Thanks for the mod recommendations tho

(Sorry if my English is bad) I'm fairly new to KSP 2 and I was just wondering where I should go or what I should do at my skill level. I've been to both the Mun and Minmus before and have even been to both in 1 mission, I have a couple of satellites orbiting Kerbin, The Mun, Minmus and Duna but now I'm not sure what to do next. I've tried a couple of times at making a space station but I'm quite bad at rendezvous and docking, I could maybe just keep on trying to improve my docking skills or go to another planet but I'm not interested in the latter at the moment. I'd appreciate some cool ideas or tips on what to do and where to go from this point.
