Show retain flag in message history

[cymplecy]

Sometimes, I see a button to delete a retained topic but other times - it is not there.

Is is a problem that my client is not setting retained flag properly (client is NodeRED) or is it a bug in MQTT explorer?

It is a common misconception on how the retain flag works and that it is intended for.
See this issue from yesterday for details #108

Thanks nonetheless for reporting what may appear like a bug.

So, reading #108 , I'm understanding that the broker only sets the retain flag on the 1st message that it sends to a connecting client. Would it be possible to add that information in the history information?

That would certainly be useful Information!
