As the number of scripts in the library grows it will be helpful to add more structure to it using categories and/or tags.

Add a "category" and "tag" field to the metadata for each script in the Octopus Deploy Library.

Change the UI to group scripts by Category.

Initial categories could include:-

Workflow (Wait, ...)
Windows
NT Service
IIS
Database
Test (NUnit, Http request, ...)
Data Collection (Disk space, CPU, ...)
Integrations (Slack, Hipchat, ...)
Network Environment (Load Balancers, CDNs, etc.)
