You can already mass upgrade buildings on one planet by pressing shift F, unless you mean mass upgrade everywhere, in which case it could be a useful feature
7. Also, can you make infinitely upgradeable research more obviously visible? By the time I found them, I had already made suggestion #5 and started my second universe.
8. Found some weird bug. For a brief moment, All the energy maximums for traveling were zero. I definitely had far more than zero energy, and the bug fixed itself after a bit.
9. For some reason, if you renew your dimension and instead of creating your starting universe, exit, and reenter, you get a savefile with no universe. (Accidently triggered on a copy of the main savefile when I was playing around with the dimensions seeing what I would get if I renewed on the main savefile)
10. Placing a mega probe constructor on a terraformed planet partially corrupts the solar system that you did it on, and makes all the planets inaccessible unless you had them bookmarked. On reload of the savefile, the mega probe constructor appears on the star itself with "View Planet" viewing the planet even though it was terraformed
11. Supercluster probes from a supercluster other than your home supercluster shouldn't have the plutonium and energy cost as if it was in your home supercluster
12. Solar Panel Auroras are only taken into account when you are on the same planet
13. The game contradicts itself with the 9001 galaxy size requirement for triangulum probes, and also giving a warning when attempting to conquer such a galaxy
I don't think the 11 solution would work, especially with something like 7999/8000 superclusters, where it would make zero sense to have a discount when instead of doing it from your home system, you literally send the probe from the other side of the universe
Also:
14. Probing superclusters after 500 superclusters takes an utterly ridiculous amount of time and is definitely bugged; 500th takes 9 days, 1000th takes 120 days.
17. You can set infinite research effect in dimensional reset upgrades to a negative number.
18. Time speed does not affect the ship travel minigame, even in a time speed = 3 universe
19. Add a way to delete universes. I triangulum probed a universe and the starting planet's size was absolutely terrible (6x6), so I am completely ignoring the universe and triangulum probing another universe. I'd like to not have the universe clutter up the discovered universe menu (this suggestion was added before my dimensional reset).
20. Upgrading a building with a low enough time requirement will freeze the building construction and make the building useless (debug console shows divide by zero error)
21: After doing a dimension reset with 0.1228 base cost multiplier, the game keeps popping up a "Are you sure?" message every time I try deleting a building (even if the building is a level 1 power plant). Happens only for the first ~20 levels
22. No scroll bar for >105 inventory slots
23. With 0.1228 base cost multiplier and 1.4 time speed: Level 2, XP: 4,447 / 16
