1) Being able to reroll the map or customize some features on it (percentage of trees for example) would be nice - I ended up with a map with a few trees on my side of the river, but they were on the opposite side of the map from my spawn point
2) Being able to see lists of resources & dwarves (with statuses) would be nice - even just a counter with the number of dwarves would help when planning out beds/bedrooms
3) Increase the scroll speed a bit or make it user definable - I know I can use the minimap, but sometimes you want to pan across your land
4) Allow a preview of the space that columns would support; you can place a column anywhere and whether or not there is a ceiling is irrelevant, but at least you'd know there is support for the indicated area - there is a Rimworld mod that does this
5) Priorities for jobs - currently I'm not sure how this is decided, but am curious if assigning only one job to a dwarf, like cooking, would help - I tried it, but it seemed that hauling water and other things still took priority or they were considered part of the 'chef' profession
