Where can I see my recently used projects?

When right-clicking the DeskTime icon on your taskbar, you will see the Projects you have recently worked on in the 'Recent projects and tasks' section. You can start tracking time for one of those projects easily from the list.

If you do not see a particular project in the list of recently used projects, click on the "Create a new project / Search for a project" option. Then start typing the project title. The project should appear as a suggestion.
