Scale chart drills practice
I've added a the beginnings of scale-chart drills. Support for this is currently limited to the study feature of drills. You'll get a prompt to play some scale and the answer portion will tell you the notes you needed to play and give you an example of how to play this along with the practice functionality from the past few weeks and allows for study
This is new territory for me, but future work around this should give the drills the ability to listen to you play a scale and judge if you've played this correctly or not.

Play-along practice tool updates
The practice tool from the previous update now works with scale charts - this make this available for all melodic-style guitar charts (arpeggios and scales).
In addition to scales, I've also updated this tool to have one faster speed (300 bpm), and the ability to select which direction the pattern is played. Instead of just ascending, you can play the pattern in descending or a sort of ping-pong ascending/descending combination - All of these make for good practice in learning these scales and arpeggios.
I've still got more planned in the future, but give this a shot and let me know what you think! Is 300bpm fast enough? Do you have ideas of how this can be more useful?
