Another issue is the complexity of switching between filtered views. A very useful primitive that you and Uptrace are missing: "show this event within the surrounding context". CloudWatch has it.
The other main overarching issue is ease of navigation and switching between contexts. You are actually somewhat better than Uptrace because I can actually cut&paste URLs on most of the pages and send them to my colleague over Slack.
But you make up for that by having bad search in traces (e.g. I can't just search all the traces with the word "UploadDoc" somewhere in them). Here's how Uptrace works: https://imgur.com/a/UWSdIEt
Your "Trace View" is ridiculous: I can't resize columns, I can't drag them to change the order, I can't even _show_ additional columns even though I can sort by them: https://www.loom.com/share/d5fa401384d94959978c0bb2be9010a5?...
Then you also are freaking annoying with the UI. I don't even care about everything getting extra-bloated. It's just par for the course for the modern UI vibe-based design.
But I get almost physically sick from these ridiculous popups: https://www.loom.com/share/21f5efdae8b84b12ba09c45cd2fa0855?...
Honestly, I think that most observability stacks (very much including SigNoz) are focusing on looking hip with cool dashboards. They totally suck when I need to dig deep into logs to find what happened.
