Yes! .. so much this.
I don't know if these threads ever get looked at by FDev but the UI for missions could really do with some basic work like that.
As for refreshing. Just make a 'Refresh' button, and people can click on that to reload when they want. It can be rate-limited so it's not spammy but that doesn't seem beyond the realms of possibility to me.
One of the developers explained why the refresh wouldn’t work as the missions are generated for everyone. If you were to refresh the board it would refresh for everyone else.
It could be done by generating a lot more missions server side than you see when you open the board and a refresh would just let you, and you alone, see the other missions. Other players could refresh as well to get more listings.
