Improved display filtering

I would like a simple way to be able to quickly toggle between different categories of route info I have saved to Gaia. For example, quickly switch between displaying my hiking routes and biking routes. While this can be done with folder visibility currently, it requires I either put all of my routes of one category in one folder (which makes it impossible to organize them in other ways like by area, etc.. ), Or I have to go through and toggle each folder individually which is not realistic for practical use. I suggest something like the following for implementation: 1. Expand the folder system to have sub folder level organization and improve the workflow speed for quickly toggling folder visibility. With this method, you could put all hiking routes under one top-level folder and toggle the visibility of that top level folder. The downsides to this method are (a) it forces your users to adopt a specific folder structure to use it (b) in the case where there are more than a few categories, the ‘toggle folder visibility’ workflow becomes inefficient. To solve issue (b), something like a ‘show data only from this folder’ function could be added. 2. Add user defined categorization tags to route/track/waypoint data. This is what many cloud photo storage services have implemented to help users organize and filter their photo libraries. It similarly could help Gaia users and would not depend on folder ops for use. This also allows users to apply multiple categorization tags to a single map object. (Activity type, state, region, year, part of a planned trip, good or bad route, etc.). This method allows users the most capability for filtering data but the downside of this is users would need to manually add that data to each object. This might be alleviated some if a certain standard set of data could be filled automatically (things like state, region, date). The IOS photos app does something similar to this.
