Projects are great, but it would be useful to group some of them into a top level organiser.
For example, I have multiple projects related to different work topics, it would be helpful to place them under a header called Work, when you click the work folder it expans with all the projects inside. Likewise, if I have several projects related to home improvements, it would be useful to place them under a header called Home.
Example:
Work
• Project 1
• Project 2
• Project 3
Home
• Kitchen Renovation
• Garden Plans
• Decorating Ideas
This would help keep the Projects list shorter while grouping related projects together.
