If you go to the welcome dashboard and click on the options button and then "Your Settings" then you'll be taken to your user settings page.
The bottom part of this page has a section called "Default Views".
These inputs let you decide which view should be shown when you go into each area of your Project.co account. You have the following options:
Projects - You can decide between the list, card and kanban views.
Templates - You can decide between the list & card views.
Tasks (All Projects) this is the master tasks view - You have the option of viewing all tasks or my tasks and also the list, calendar, scheduler & kanban views.
Tasks (Inside Projects) this is when you're viewing the tasks tool inside a project - You have the option of viewing all tasks or my tasks and also the list, calendar, scheduler & kanban views.
Whatever options you select will be the default view type when you go to each page. So if you want kanban to be the default view for tasks then you can set that to be the case.
Note: Bear in mind that these options are set per person and don't apply to all people in the account. We don't have a way to set these defaults for all users at this time.
