Feature request: add buttons for predictions for common times

[Sha-yol]

Like in the yearly prediction page, where there are buttons for "3 months", "6 months", "End of year", etc. Some things I would find useful:

1. By next week / a week from now
2. By next month / a month from now
3. By next quarter / a quarter from now I do those periodic predictions every week/month/quarter; maybe surfacing those buttons at the relevant times would be even better, so they don't clutter the UI. That would require getting the start of the week correctly depending on localization; might not be worth the hassle.
