Can someone let me know if there are any plans to improve the features for managing functions in CRM?

I have lots of functions and finding them is hard. The search only works on the function name and the filter only works on function type. I have created a naming convention based on tags to filter the list which helps a bit and for some projects I keep lists in a spreadsheet. 

I'd like a spreadsheet-style list in CRM with a few custom fields and a way to construct views (like in modules). Maybe even make functions module with layouts etc?

Also it would be great to be able to search for text within functions. A use case is that I'd like to be able to tidy up API names but without a reliable way of finding where they are used it's too hard. 

Very grateful for thoughts on this
