Felt this deeply, we were in the same position after going remote and spent way too long forcing existing tools to do things they weren't built for. The 60% coverage thing is so accurate, the remaining 40% is usually the stuff that actually matters for how your specific team operates. Found custom software development services through a forum recommendation and what surprised me was the pricing was actually reasonable for what we got. They scoped it tightly based on what we genuinely needed instead of upselling everything. Been running the custom setup for about eight months now and it's made a noticeable difference.
