Option to set test target length

[Pantman]

I'm a beginner, and have been using Sight Reading Trainer for a little while. It seems to be the best resource for learning how to recognise notes!

It'd be great if we could set a target for a sight reading session - say a certain number of notes. Currently it goes on forever - it'd be awesome if I could set a target of X notes. The 'game' would stop once I reach X, and give me my score (percentage of hits vs misses).

It'd be also be neat if this could be saved so each time I visit the site, I can try to improve my score, before tackling a more difficult challenge.
