[Feature request] Docsets Scenario Preset: allow user to enable partial docs in all installed docsets

[JustusPan]

Imagine following scenarios:

1. I'm working base on C++/C during day time mainly
2. sometime I need develop a project which is made with Unity
3. when writing some notes and articles, I need LaTeX reference
4. at a weekend I want to grab up Python quickly

there are many docs installed in my Zeal, but I don't want to see all of them at all time

• C++
• C
• Qt6
• Vim
• Unity(Unity need multiple version doc, this is another topic)
• LaTeX
• Python
• Godot

Could we support a feature which allow us to only activiate specific several docs from those all installed?
this feature consists of 2 phases.

1. just allow user manage(enable/disable) installed docs in docsets settings.
2. create a "quick switch preset" feature for your predefine scenario, and you could use shortcut Alt+1,Alt+2,...Alt+9 to switch between them quickly.
