I mean what more do you want? Missions already have a little feature that lets you click to jump system. If you set destination, it entirely maps out your route based on your parameters and all you need to do is click on the next gate in your overview (which is highlighted yellow and at the top of your overview) and hit the warp to button, or use the hotkey for warping to. Navigating a route is not a manual process.
Yeah, ever since I’ve been playing this game, CCP has had the bad habit of constantly making everything super small, especially the scroll bar and close/minimize icons for all the various windows in-game… Probably due to them viewing the game on a wall sized monitor…
Anyway, as for the icons in the ‘Selected Items’ box, try resizing it both vertically and horizontally, there’s a sweet spot in it where the icons will enlarge making it easier to select them without making the box take up too much screen space…
