This is sooo needed!! And I'd add a little hourglass to those missions that are delayed (vs the one that are instant) and I think I'll dare to ask if it would be possible to identify the short (<15 minutes), medium (<4 hours) and long (>4 hours) missions. That could be done with wooden, silver and gold hourglasses as small icons...
To me, mission selection is a bit of a mess now and I just keep clicking everywhere to find the one I want to do!
Oh! And more constrasting icons for done vs new missions! Now it's silver vs silverish with a tiny glimpse of color... It's rather difficult to find new missions in a blink of an eye... (tough you know it's from the last few ones on the line..)
Also, when finishing a 3D mission, I'd prefer having a "Restart" button than a "Next Mission" button. Yeah, it's cool to revisit many mission in order, but when I want a particular item, I'm redoing the same mission again and again! And this happens much more often than doing missions in a serial way...
Also, I'd like to quickly scroll through campaigns. I don't really like the campaign selection screen, because it don't even scroll automatically to "Current Campaign" when on first opening! This would be a minimum...
However, better than this would be to add arrows to the campaign's title to scroll to previous / next campaign. This way, with a few clicks/taps you can browse all campaigns! This could be also done by sliding the screen left or right, but I don't know how it'll feel on Chrome.
I'll also add that having a bit more style and diversity on campaign backgrounds would be welcomed! To me it's very static (I know it's not the same image over, but it doesn't have any identity imho... ) We do pass a while on them, and it would be great if we'd be happy to get on a new campaign just to see what it will look like! For now, I'm just happy for the achievement and a bunch of new missions...
As for the 3D missions, when you use a power, it's very unclear to me how much time you still need before it comes available again. I think I've seen something evolving with the timer, but it wasn't very clear. I'd suggest a red filling or unfilling bar to easily keep track of the timer. I don't know if it would be clearer having a vertical filling (bottom up) or a radial one (clock style), but any will be better than nothing (or any constrasting enough if there's already such thing on).
Finally, I'd like to be able to see quickly my energy count or timer, and xp to next level! For the first one, energy, maybe when clicking/tapping on it you could display current energy with the timer besides. You have sooo much free space to pay for refill!
And for the second one, XP, it comes from last patch: you had the total XP to reach in the bar. However, I guess the bar was too small when on high level, thus the change in current XP progress. That's fine, but why not giving the needed XP count instead? It's a tad less intuitive, so you could add "needed" for first few levels (with smaller numbers, this should be ok), but it would give useful information instead of that "random value" with no purpose to those who can't remember what's the next XP goal.
So, quick recap:
1. Hourglass for delayed missions (could be different depending on delays)
2. More contrasting new/done mission icons
3. Restart button upon 3D mission completion
4. A way for quick scrolling of campaigns
5. More love to campaigns' backgrounds
6. Energy level and timer in the "Refill" dialog
7. Clearer timer display on powers
8. Show the XP needed for next level instead of current XP
