Support for sub-folders of main tasks folder in Office365
Plenty of people use subfolders inside of their main task folder and categories are not the best solution for marking folders. Moreover Microsoft To-Do organizes tasks folders as subfolders of the main task folder. Therefore allowing for syncing tasks from subfolders seems like a meaningful idea.
What's more there is no Kanban-like view in MS To-Do for Windows but their mobile apps for iOS / Android are beautifully simple to enter new tasks and check ones today's tasks. Hence to maintain "competitive advantage" 2day should give its user possibility to use MS apps on their smartphones and deliver amazing desktop experience. To make this work MS To-Do apps and 2Day have to be compatible, which in the simples possible setting implies allowing for syncing tasks across subfolders of the main tasks folder.
