More features needed

[klntsky]

This piece of software is cool, I personally use it on daily basis.
But could you please implement some more features?

What I think is currently missing:

• PgUp/PgDn & Home/End navigation
• reading JSON from stdin (to pipe output from other programs)
• text searching

Also, README says that close toggle and open all json are bound to F2 and F3 respectively, while in fact it's Q and E.

Also2, it's better to use Q hotkey for exiting because it is common among the majority of TUI programs.

I am sorry to see your reply todayand thanks for your advice so much😄.
This is my practice last summer, so It exist so many problems.
But after completed, I did't think about making it better, it's a bad habit for a programmer.
I'll try implement your perfect suggestions recently.
Thanks again~
