I'm sorry as well.
People didn't vote for the suggested implementation, but going up to the problem level can help bring in more voters.
I suggest you re-post the idea as "Ability to hide certain notes from view by default", which seems to be the most generic phrasing. It doesn't limit implementation to tags, special kind of tags, etc.

Fixed again in 3.0

Released in version 3.0!

It is! If you've seen our recent survey and its results, we are going to prioritize this feature quite soon!

Burrum, really glad to see that you're still with us! :))

Still no luck properly reproducing the issue ;(
Does it happen after you start CN manually by clicking its icon, or only when CN autostarts with the system?
Maybe you could send your cintanotes.settings file to support@cintanotes.com? Thanks in advance!

A new beta with this feature is coming soon! Still ironing out syncing issues, for details please see here:
