[Feature Request] Don't redistribute cards with manually set due

[hsseek]

I adjust due dates for some cards. For instance, while the suggested due is 27 days and my exam is in 23 days, then I'd adjust the due date to 20 or so.
When I Load Balance, the due dates are adjusted as a whole, so the card that I deliberatedly arranged on a specific day also are moved to another date. Also, Anki does not provide search options to filter cards with manually set due dates. So, my former arrangements are missing forever.

Describe the solution you'd like
I'd like an option to exclude cards with manually set due dates on Load Balance.

Describe alternatives you've considered
Load Balance on deck-wise would be great as well.

The main problem is, it's impossible to distinguish manual set due date and reschedule cards on change. So if you enable reschedule cards on change, the helper add-on will not redistribute all cards.

If I Reschedule cards in n days then it would reshedule all the cards reviewed in n days, including cards with manually set due dates, after reviewed in n days. So the cards wouldn't appear on the dates I set, instead, it would appear on the dates that add-on redistributed. Am I missing something?

Oops. It's unintended. I find out the problem:

fsrs4anki-helper/schedule/reschedule.py

Lines 232 to 237 in 18e9ec3

	if recent:
	today_cutoff = mw.col.sched.day_cutoff
	day_before_cutoff = today_cutoff - (config.days_to_reschedule + 1) * 86400
	recent_query = (
	f"AND id IN (SELECT cid FROM revlog WHERE id >= {day_before_cutoff * 1000})"
	)

Because set due date also generates revlog. I will fix it soon.
