[Feature Request] Tags sidebar with nested tags

[HorusPi]

For those snippets marked with more than one tag, would be nice to have nesting so you can drill down and narrow your focus.
Broad idea

• All snippets that have only one Tag , remain as they are.
• Snippets that have more than one tag have a [+] mark that allow to check on all the other snippets that have the same tag and another one.

So if you have a snipped tagged as ".Net","Docker","Automation" you still get 3 entries

.Net[+] -> Shows all .Net tagged Snippets
. Docker [+] -> Shows all .Net & Docker Snippets
. Automation -> Shows all .Net, Docker & Automation Snippets
Docker[+]
. .Net [+]
. Automation
Automation[+]
. .Net[+]
. Automation
