Feature Request: Hashtags visible in sidebar

I love using hashtags to add additional context to my to-dos, and would be able to use them even more efficiently if it were possible for hashtags to appear in the area of the sidebar where custom lists currently reside. As things stand, I have to either type the hashtag into the search field or find an existing to-do item with the hashtag whose other family members I want to see. 

Please consider incorporating this feature. Thank you.
