I’m keep on doing refining the Settings page, under home/spaces_dock.rs.
I have finished reloading the Dock.
In the match block, I put *APP_PAGE.read().unwrap() outside while *APP_PAGE.write().unwrap inside, which is a deadlock.
Fianlly, I put the *APP_PAGE.write().unwrap outside the match block, and it works.
VK pair debug = "full" is not necessary for me,
it consumes a large amount of disk space while the log! is good enough, which just can not be affected, behavir normally.
