Sorting by "Rank Achieved" offers a similar functionality. It's not exactly the same, but it serves roughly the same purpose - if you want to find maps on which you have really bad accuracy, go through the maps on which you have a C or a D.
I'm not sure exactly what you're looking for with this request - would you want Sort by Accuracy to
- put all beatmaps you've passed in order of your accuracy?
- put maps into groupings of 99-100%, 97-99%, 95-97%, 90-95% etc?
I feel like the latter would be more useful (once you've passed enough maps, it would be somewhat difficult to work with just a strict listing of them), but I feel like it has fairly significant overlap with Rank Achieved. For example, on the low end of things (which is what you seem mainly concerned about), if it gave you a range of, let's say, 70-75%, I think you would be just as well off looking through your Cs and Ds as you would looking at that specific accuracy range. In fact, I would argue that, if it's "accuracy" you're concerned about, the letter grades are more useful. Since letter grades tell you roughly what fraction of 300s you get, a lower letter grade will more often correspond to poor "accuracy" than a lower percent will, since the percent is influenced more by misses than your letter grade is. However, I can see this being useful for higher ranges of accuracy, for finding 97% plays that can be improved to 99% or 99% plays that you really want to SS.
Could be useful with the right implementation. I kinda like it.
