Hey
@hritic333 I think it would be a cool feature.
However, I don't need it, because I think the opening explorer is great enough for that. You can explore your games through the opening database and not only reach those games you want in a specific opening but also see statistics on how you perform, what moves you've been faced against, etc. When trying to learn from my opening mistakes, I also find it helpful to go back and forth between my personal database and the global lichess database to compare and find other popular alternatives to my moves.
I hope this helps you while that feature does not exist :-)
