Feature Request: General :Fzfx command

[jam1015]

would open a popup menu with all fzfx sub commands, and descriptions of what they do.

kind of like the general :Telescope command where you can then pick the sub-telescope commands

hi @jam1015 ,

This is more about the product design. When I first create this plugin, I followed the design of fzf.vim, which also contains multiple commands.

The Pros:

• I can see that, a general :Fzfx command will reduce the plugin's initialize time, because it will register only 1 command, instead of so many (FzfxLiveGrep, FzfxCommands, FzfxFiles, etc).

The Cons:

• If we re-write this plugin, it will bring a lot of break changes.
• And I don't feel it makes the usage more user friendly.

let me think about it, I will pend this issue for now.
