1. Repair pack: "repair speed: 2" - 2 what? It should be "2 hp/s" or similar.
2. Assembler "crafting speed" similar, but it's a multiplier? "0.7x"
3. Inserter, I know the friday fact, maybe it comes with a speed with the rework
Other small things, that anoy a little bit while playing:
4. The Tag "Train Stop" should be in a seperated line to the actual train stop name, just for readability.
5. Fell a tree while walking towards it "out of reach", may just pop this message instant or even wait if I'm about to reach it.
6. Moving while deconstruct, i.e. a belt line, below the character lets the flashlight flicker. It's not needed to turn half to the belt for 0.1s for deconstruction imho.
QoL ideas while playing:
7. With an active ghost in hand opening the inventory could show the recipe page for that item, may be highlighting the item itself.
8. free form selecting bp / cut, maybe with shift? how often there are some things you want to copy, but an other production lane is crossing.
9. Add "squeak through" Mod to vanilla
may with reduced movement speed, but not be able to climb over pipes or fit between buildings is "unrealistic" 
I collected this since 0.17.34, may there are already improvements I didn't realize, sry. And I hope nothing I blame is added by mods
Thx for reading and keep up the good work, love the game
