- Keep ideas available for a later planning session.
- Use reactions to limit noise in the library.

- 2Create an automation through the portal or ask Notis conversationally.
- 3Write one plain-language instruction to add reacted-to idea messages, with their stated context, to the idea library presentation.
- 4Pick the Slack message reaction added trigger and configure the chosen emoji or channel if useful.
- 5Choose a channel for run reports and test with one real idea.
Questions about this workflow
How do I keep routine reactions out?
Use a dedicated emoji for ideas and optionally limit the trigger to the channel where ideas are shared.
Will Notis rank the ideas?
The workflow can collect them; rankings should be based on criteria you state explicitly.
