Hello all,
Just following up on the message above in case it got lost. I’d appreciate any thoughts on whether the direction I’m exploring around manualintegrate makes sense, and what a good next step might be for someone interested in contributing in this area (for GSoC or otherwise). The Ideas page <https://github.com/sympy/sympy/wiki/GSoC-Ideas#rule-based-symbolic-integration> mentions that potential contributors should "Discuss with us" in case someone is interested in smaller projects to just improve manualintegrate, so this is the discussion I would like to initiate. Thanks, and apologies for the nudge. Best, ButteryPaws.
