Mostly when going through my materials I find it a bit annoying that the list for it is so long in my Arsenal. Having to scroll through it in 1 column really takes a while and makes it easier for me to miss the material I'm looking for.
I think it would be very useful if your Arsenal had an "Expand" button, which would enlarge your Arsenal with an extra column or 2. It would give a much better overview on your inventory in my opinion.
I'd also like an option to sort my jank (especially materials, recipes) by star value instead of alphabetically by name
