Blues Guitar Backing Track in E Major (For Improv Practice)

Here I'm trying something new. Other backing tracks out there show the scale diagrams and usually the 1st position of any given scale is highlighted. Otherwise they just show you the chord progressions or nothing at all.
Here I show the Major and Major Blues/Pentatonic scales. With Root notes, chord tones and blue notes assigned to a colour system for ease of use while practicing improvisation and tone targeting.
Afterthought: should I let the scale switch to match the corresponding chord in the backing track and let it follow the backing track? Also should I let the scales switch faster than 20 seconds? I would appreciate any input to perfect this idea. Leave them in the comments. Hope you guys enjoy.
