Drag and Drop seems really inconsistent throughout the whole app, which is confusing and unnecessary. Tasks should be able to be drag and drop-able to other lists etc. no matter in what view I am. It's confusing i.e. that it's working from List view, but not in Gantt view. Super confusing, that it sometimes works and sometimes not (another example: you can't drag tasks in lists that are in your favorits, seemingly no matter in what list you are).
