The current method of using a radial menu to place markers is very clunky for mouse and keyboard users and very inefficient and confusing compared to the Arma 3 method. It's especially weird because the "custom marker" dialogue box is much more useful but you have to jump through hoops to get there.

Please have something like Arma 3 for mouse and keyboard users, and/or allow for using boxes and lists. This could be a user setting if autodetection is too hard. But currently it's VERY awkward to use.
