I agree, I would love this function too. For example I would like to set a repeat for example every 2nd day or certain weekdays. For an organized homekeeping that would be amazing.
Indeed drag and drop tasks on the agenda view would be a great addition so that I can just put in the order the tasks need to be done.
That would be a great idea and would help to replace a lot of my extra apps so I could just use 1 instead.
