I get you, it’d be nice to click on tags and combine them easily for quicker search.
Currently in version 0.9.1 I use combined tags search a lot. The way I do it is by putting the following in the search bar:
tag:#bugs tag:#feature-requests
you could even search it just like this
#bugs #feature-requests
The difference between searching tag:#example and #example is in explained in the help ? section inside obsidian, if you search for “Work with Tags”
Hope this helps!
