+You can add custom fzf options for `forgit`, including keybinds, layout, etc.
+(No need to repeat the options already defined in `FZF_DEFAULT_OPTS`)

 ### Tips
 
 - Hit `q` to Quit from full screen preview any time.
 - Install [`diff-so-fancy`](https://github.com/so-fancy/diff-so-fancy) to have better `diff` output.
+- Call `glo` with arguments to get logs only related to these files or directories(eg, `glo main.go test.go`).
 - Call `gi` with arguments to get wanted `.gitignore` contents directly(eg, `gi c++`).
