Fixed "Multiweek" / "Upcoming weeks" (next 3 weeks) grid view mode
Originally filed in GNOME Bugzilla #700662 by @jfft
I suggest combining the look of the "month view" and the use of "list" view, and create a new "upcoming" view.
The concept is simple: squares just like a month calendar, but do not show the weeks previous to the current one. Show only the current week and the 3 weeks that come after that (this number could be configurable).
Rationale: most users don't care about the past or about which month they're in, they just need to plan a few weeks ahead.
Optionally/ideally, as the backend would allow it anyway (since it would be needed for the implementation to work at all), there could be a spinbutton widget in the "hamburger" menubutton that controls the number of weeks shown in grid/multiweek view; if you want to keep that menubutton simpler, that spinbutton could be shown only when inside the grid/multiweek view.
This is mostly an easy "stepping stone" stopgap solution. The hardcore / ultimate solution is implementing #603 combined with a configurable height in terms of "number of shown rows".
