Can I order Projects or Labels?
You can reorder your projects by hovering over a project's name and then using the handle which will show up on its left side.
Unfortunately, you can't reorder labels, they're always automatically sorted by the amount of tasks which have this label.
Can I order projects on my devices (iPhone or iPad), or just on a computer? online?
Reordering projects is available on the iOS app too. To do so, please tap on "Projects" and then on the pencil icon in the top-right corner. This will allow you to perform various actions incl. deleting projects, editing them, but also reordering using the handle icon in the right side of each project. Once you done, tap on the check mark (which replaced the pencil) to exit edit mode.
The option to reorder labels according to 1) number of tasks associated and 2) alphabetically, would be great.
I just paid for the premium service. I'm thinking about switching over to Todoist, but I'm disappointed that I can not re-order labels in the same way as I can re-order projects. Also, I wish I could next labels. I like to have a label called, "errands," then nested under it I have "home depot" and "grocery store." Is this something that might change in the future. It seems natural that projects, labels and filters would all be sortable in the same way. . .
