I think that it's normal to usually have a couple of spaces/projects/lists that are focused/most active over short periods of time (days/week) and "flipping" between them constantly (keeping a few tabs open works only to a degree).
This "flipping" is currently quite cumbersome: opening the spaces pull down -> finding the space (how is it sorted there?) -> finding projects -> filtering/sorting.
I guess this could be improved in more than one way, but for maximum gain with minimum work, would be nice to have starred spaces/projects/lists as quick links under the pull down menu of the spaces (ideally, with a persistent view, including selected project/list and sorting/filtering).
