When you use the #next hashtag, ResultMaps moves the item to the top of any contexts where it appears. Examples of these contexts:
Your personal day plan (if applicable)
The list of everything you've asked others to do (if applicable)
If you have other items in those contexts that are not tagged #next that you want to reprioritize, you can remove the tag:
Click the wrench icon at the bottom of the screen.
Click Clear all #next tags.
From there, you can reprioritize the items as desired by dragging and dropping them or by using any of the relevant button options (e.g., the upward arrow to move an item up on the list, etc.).
