A suspended WAL table is a serious issue, indicating something nasty happened.
It's also a common cause of user questions. As a QuestDB user, I would like the web console to highlight suspended tables. It should be very visible, attention screaming. One option could be a red exclamation mark next to a table:

I would not be afraid to introduce a brand new notification mechanism for critical issues like this (low disk space could be there too). But that would probably require a bigger design effort.
Whatever we do it should be actionable. It should inform users about:
- What happened (error while applying a WAL, often happened during a power cut, etc.)
- What are possible solutions (alter table resume, link to https://questdb.io/docs/reference/sql/alter-table-resume-wal/)
- What to do if tables cannot be resumed (fill a bug, ask at Slack)
