I'd add to this that there should be two different repeat parameters--a start date repeat and a due date repeat. For example, I have to renew my vehicle registration by the end of the month in which it expires every year. But, I can't start the renewal process until the beginning of the month. So, I'd like to have the ability to repeat the start date for the first day of that month yearly and repeat the due date for the last day of that month yearly.

Really hoping this gets properly implemented - I find that a significant proportion of my task list is typically composed of this type of task (the vast majority of all 'maintenance' type activities and other routines fit this pattern), and without this natural treatment of start dates the list quickly becomes unworkable.

Would love that feature and like Joshua mentions I think there should be two repeat options

I'd really love this.

I'm disappointed this hasn't been implemented yet. It's the one feature that makes me regularly re-evaluate continuing with RTM.

I'm surprised there aren't more people asking for this. But I'm also surprised how many task managing apps don't do it as sowens expects above, so maybe my use of start date without due date is not very commmon. I was looking to switch from a competitor, but I think this is a deal breaker for me.

I agree totally. The vast majority of my tasks fall into the category of repetitive (after) but do not require a due date. The current implementation requires me to eliminate the due dates for each of the repeated tasks.

I really wish RTM would increment start dates on repeating tasks. Just apply the same logic for the start date as is used for the for the due date. And if the original task has only a start date, then the repeated task should be the same.

It seems like this should be an easy update, but would it mess anybody up?

For sure this would greatly help those of us who use start dates to indicate when we want tasks to appear on our radar, and only use due dates when there's a true deadline.

Yeah, a big reason I use RTM is because I use due dates strictly as real due dates. Therefore, I use starts dates a lot for my workflow.

Most of my repeating tasks do not have a hard due date so I need to repeat off of a start date. The due dates required for repeating tasks detracts from those tasks that have a hard due date and must get done that day.

Totally agree with this. There's a moderately annoying work-around, but I'd love if I could just mark a task as complete and have the start date push forward whatever days I set.

My workaround is just to put in the notes how often I want it to "start repeat", and when I'm done rather than mark it as complete, I just change the start date manually using the notes as reference.

This feature would be very helpful for me!

I agree. This would be useful. Like jogo1 said: "if the original task has only a start date, then the repeated task should be the same."

So...
If there's only a due date, the repeat should adjust that due date without adding a start date (like now).
If there's a start date and a due date, the repeat should adjust both dates by the same interval (like now).
If there's only a start date, the repeat should adjust that start date without adding a due date.

I'd use this too, and it doesn't seem like it would break anything.

I agree with this idea!

In addition to my workaround above, I often duplicate it, complete it, and then change the start date on the duplicated task. This is so I have a history of the task being done, rather than just the same task moving start dates.
