Interface similar to Wunderlist, functionally not the same unfortunately. As an example, Wunderlist allows manual sorting after sorting by one of the sort options (alphabetical, etc), which can fine tune things beautifully. Microsoft To Do does not allow manual sorting unless you deactivate the selected sort (like deactivating alphabetical sort as an example). This then reverts everything back to the same unsorted mess prior to the selected sort option. Very frustrating.
