Add ability to sort 'manually'

[thibaultmol]

Problem

Currently in the app you can only sort by your recommendations you've set. But I would like to sometimes just select the one with the lowest kcal and go from there.

Proposed solution

Add an ability to override de 'recommendation' algorithm and just manually sort by specific values. like kcal.

@thibaultmol I understand the general idea. I see for nutrients, but are you also thinking about other data?

[thibaultmol]

I guess it's mainly for nutrients data yeah

[monsieurtanuki]

Setting nutrients to sort on (ascending or descending) shouldn't be a problem.
The display should be discussed, because I presume you want to see the values, and that may mean a totally different page (like a table), especially if you want several nutrients at the same time.

In addition to that, that's a bit in contradiction with "our" scores, like Nutriscore.

Could you please give a real-life example of what you'd like to achieve? E.g., "my scanned yoghurts sorted by descending proteins"

[thibaultmol]

Basically one of the things I wanted to do was scan all the things you'd consider 'snacks' in my local supermarket and then sort by kcal. See what's the lowest. And then look at the top 10 of those what their other nutriant values are. for example

That would mean ordering by only one nutrient, and then you click on each "top 10" product for more details, right?
In that case do you need the value in nutrient in the list, or just ordered products you can click on is enough?

[thibaultmol]

I guess both? Being able to see what the actual value is that it's sort on, on the item itself while in the list view would be nice.
Cause it might jump from 50 to 150 all of a sudden but they're right next to each other. So I might just cut off the list before it jumps to a much bigger value.
