like for example clicking these little up and down arrows:

clicking it once makes the value jump like 20 mm, which really isnt good since my model is like 20mm wide in total, so itd be nice to be able to adjust it with slightly more accuracy

you can adjust the precision of these value fields (called spinners apparently) from the preference settings > general tab > spinners. Precision lets you control the amount of decimals in the spinners, and the snaps value seems to serve as sort of a multiplier for how much the value changes with each click (unfortunately doesnt change the adjustment speed when dragging the slider, but ctrl/alt helps with that)
also if you click on the value, and press ctrl+N, it lets you input an expression in to the spinner which is totally rad.
