Calculate task progress percentage by number of items done
Steps to reproduce
None. Feature request.
Expected behaviour
Add possibility to set task progress in number of items: 0 to M. Default - 0 to 100 (as percents).
And use slider to set current number of done items.
This will recalculate percents / progress-bars.
Variants of progress view could be switched via radio element in right panel.
Actual behaviour
Not implemented.
Server configuration
Any.
Client configuration
Any.
Logs
None.
#139 seems to be similar.
As I understand it, you propose what is requested there PLUS that sub-tasks are marked as done if one would set the slider accordingly, correct?
Example:
Task with two subtasks, radio button is set as 0 to M. Slider is set at "50%". First Sub-Task is marked as done.
No, it's not about subtasks. I'll try to do some illustration soon.
Made in dev tools:

The idea is in that checkbox. It switches result text that rendered in not active row and first text input:
- if checked (by default) - text "$N % complete" rendered
- if not checked - text "$N of ($Max-$Min) items complete" rendered
This can look ugly (UI). Maybe better add row above with that checkbox switch and min/max settings.
Something like this:

If there is planned to use subtasks as "progress items" then there additional checkbox-input can be used. Like: [x] Show progress in percents [x] Use subtasks as progression items
Maybe such UI should be in "dropdown" panel inside "%" row. For example, by "cog" button before "done" in right buttons group.
I like the ideas discussed here, but I want to offer another option, that is my idea.
I would also like to use sub-items to aggregate the super-items progress. I would not use the number of done items, but add the possibility to add weight to a sub-item that gets concerned when calculating the super-items progress percentage.
Example:
- super-item [weight: 100%, progress 25%]
- sub-item 1 [weight: 25%, progress 100%]
- sub-item 2 [weight: 75%, progress 0%]
The default value of the weight could be 100% divided by the number of sub-items, so it would also be compatible with the ideas form above.
The main difficulty I see is the recalculation of other weights of same-level sub-items if the user changes a weight, to assure that the sum stays 100%. But I would also be happy, if weights of the same-level getting added up and are used to calculate a percentage.
Example:
- super-item 1 [weight: 1 ⇒ equals 33%]
- item 1 [weight: 2 ⇒ equals 25%]
- item 2 [weight: 2 ⇒ equals 25%]
- item 3 [weight: 4 ⇒ equals 50%]
- super-item 2 [weight: 2 ⇒ equals 67%]
