Idea for new chess.com feature

An important part of chess is chess openings, hence why alot of chess players study them. However, the "studying" for many players is the equivalent to reading different kinds of move sequences. The move sequences you have read unfortanetly do not get practiced as much as they should have and you simply end up not achieving the chess education you diserve. If there only was a way to practice the openings you were learning.

Early this year I tried out the Magnus App, going through all the levels the app had to offer. I realized after a while of attempting the different levels that each level had a set amount of playable openings. After playing against the app over and over again, I suddenly started to master playing against its openings and eventually the Magnuses got defeated.

This experience enlightened me with an idea: What if there was a feature that made it possible to play against computers (varying from level 1-20 + komodo as the chess.com site has today), but where you could select among different openings (one or more openings) that the computer played. Playing lower level computers would allow you to handle the game when the computer all of a sudden does a minor mistake while higher level computers would really test your opening knowledge (as well as mid- and end-game knowledge obviously). Practicing this way would make you learn and systemize both, the opening theroy and how to act when the opponent struggles with the openings.

i think this is a great suggestion
