I remember when game was released and HUD options lacked a lot optional features or settings, for example even if you had Enemy & Rebels disabled, they still showed up in minimap. After a while they added more options which made it better, but, there's Notifications setting that would benefit from additional option.

There should be option that doesn't show near by missions. It's just a distraction in a HUD until you hold M to select that mission and it spoon-feeds you "important info", that you wouldn't always notice without opening map or knowing that it's there (especially if you have minimap disabled), for example if you pass Rebel Side Op, you would know that it's there because it shows up on your screen, or that there's a Convoy near by. Besides, if you hold M to select it, and you do not have Mission Reminders, Objective Markers or minimap enabled, nothing basically happens in your HUD, you're just forced to select it to get rid of it.

One might ask, why not just use 'Off' setting then? Because if you still want to know when you leveled up, which item you picked up because you were too busy fighting to remember what you were after, how much resource you gained, or if you need to level up Tier. Am I nitpicking? Maybe, but considering how much they tweaked HUD options vs release version, my request wouldn't be too much to ask for.

TL;DR Notifications HUD settings needs additional option to show all the info it does by default, except for 'mission near by'.
