I guess the thing is, the more you can have in one dashboard, the less clicking around you have to do. Also, one thing I've found is that those services are location specific - they often don't show accurate charts for different territories.
The Retza remix of Melt is good example. I have screen grabs that it made to No.5 in Deep House releases, yet only showed at No.6 on all the chart sites. I emailed them about it and they said it had to do the territory they were tracking.
Inside Proton would make it super easy to prepare feature requests and the like, but totally understand it's not super high priority.
