Are you working with the Kanban method? In Freelo you can create a Kanban Board/board with columns. To-Do lists or particular columns can be named according to phases of the tasks such as Inbox, In progress/WIP, Done etc.
Switch on the column view on project detail. Go to the red To-Do lists section and on the right is three-dot icon for setting > Change listing. This will automatically switch on redirections straight to column view that can be canceled also within the three-dot menu > Redirect to To-Do lists.
Freelo will remember the next time you see it in the columns for the project, so you will not have to set it up anymore. You always click on the To-Do list
Now you can start moving tasks between columns according to the current stage via drag&drop function.
