So, late to this party but here's what I would like to see happen. Star Trek: Legacy with Captain Seven on the Enterprise G can get corrupted or co-opted or lost in time. It's not beyond them being used by the Temporal Investigations division. Since in the past Star Trek has largely used time travel to completely change a given timeline leaving no Trace of that which came before, perhaps Seven's mission is to clean the timeline. They can travel back and forth to different eras. We can see different crews and events. They can be the unity between disparate timelines and time periods.
It would be nice if that wasn't the go too. I think it has become an automatic thing for Star Trek, which would be ok if, big if, it could be used well. But, for me anyway, it's a story writing device that long overstayed it's welcome.
Time travel is certainly more common in the franchise than it used to be, but as I've thought about it it was in TOS kind of a lot...TNG (until FC) and DS9 pretty sparingly, and then we saw a larger presence of it in VOY and ENT. So, it's been a part of Trek for a while with mixed results. P+ Trek definitely has the most I think...maybe the "final frontier" doesn't feel as final so we have frontier inflation and it's time now.
Back to the 24th century. But with a better show than Picard. A lot of loose ends in the previous series, like TNG, DS9 and VOY to follow up.
Tie up some but also continue some threads. That era of trek introduced a lot of lore and I want to see some of that continue
