Hi 鈴木さん, Werner and Vincent,

Indeed, that's my initial idea. I can imagine doing this as an optional 
task near the end of the GSoC session, if possible (e.g. I install a 
older version and fix all errors with conditional compilation). Before 
that, if you have difficulties getting the latest version for testing my 
code, a VM would help I presume. I could share my Kubuntu Hyper-V image 
if needed.

This has been already done on the `gsoc-2022-chariri-3` branch, see 
commit `6b79a1f4`.

As for the EFL toolkit, I'm afarid that it's too late (already ~6000 
SLOC of Qt) and it's a pity that I have no experience about that...

Cheers,
Charlie Jiang
