Do want to learn something new or stick to your path?
For sticking to your path look at J. Bartholomew's free repertoire 1.d4 on chessable. For something new get Giddins repertoire book 1.e4 with IQP positions. Both are good and comparatevely small, but sufficient at least for online chess. I tried and try both of them, slowly adding additional lines.
