Add UI for estimating time and spending time

Description

While slash commands are useful, the time tracking section of the sidebar begs for an interactive UI to add time estimated and spent in a user friendly matter, reducing adoption barrier. Time tracking is boring enough a thing to do, it should be as enticing as possible.

Proposal

  • Add a dropdown within which to input estimated time
    • if someone can think of a nice clicky UI, go for it
    • otherwise, if spent time is to be entered in a text field, there should be live feedback on how the input was parsed before user confirmation and persistence (think like labels dropdown)
  • Add a dropdown within which to input spent time and on which date
    • if someone can think of a nice clicky UI, go for it
    • otherwise, if spent time is to be entered in a text field, there should be live feedback on how the input was parsed before user confirmation and persistence (think like labels dropdown)
    • possibly add #42465 (moved) and #42467 (moved) into the mix
