Having just spent an embarrassing number of hours on the first game here's what I would like to save a little time.
Harvesting mutators permanent:
Rock cracker, grass master and hauling hero could be made into milk molar upgrades as they have no impact on combat, this would save constantly switching mutations.
Customisable radial menus:
I miss being able to quickly switch mutations.
Also the d pad down menu with open inventory, crafting, map and hot deposit (this also frees up the option to hot deposit into a single storage box.
Grounded 1 had multiple pages of hot pouch which was nice.
I realise there are other menus assigned to the d pad in 2 but the option to customise would be nice.
Eg as a solo player I've never used the emote menu so would like to swap it out.
"Hot sort"
Say you've got twenty chests with mixed contents.
Open a new one, add a peblet and click hot sort.
Now all nearby chests send their peblets to the new box.
I also preferred having separate buttons to deposit/retrieve one item and a stack rather than the slower hold option.
Cheers!
