I have been using it for a while now. My account doesn't have any high combat stats or many quests done so I cannot comment on the PVM helpers, nor can I PK, so I haven't tested out their PVP helpers as well. For skilling, there are many helpful features, my favorite would be the Menu Entry Swapper which allows you to change the menu order for items to make it easier (ex; construction). RuneLite+ is just a fork of the actual RuneLite github, which means that they code found in RL+ is the same as the original RL plus their (RL+) extra plugins. Now that does not mean they could add something to 'log' your information but the community is very nice and helpful and I doubt they would do that to their many users.
