workspace swtiching problem on multiple monitors scenario

[kouryoubon]

I guess it is not a problem though, but the default config defines workspace 1 to 9, so the default workspace for the second monitor will be 10 (11 if the workspace 10 is defined in config file), but how should I switch to the workspace 10? the config file also has on-focused-monitor-changed behavior defined, which is good. But since I cannot switch to workspace 10 using my keyboard, I would have to use my mouse the switch workspace, which seems to me conflicts the purpose of windows mangaer.
Now I know I can bind some other key combinations to swtich to workspaces whose numbers are greater than 9, or I can reduce the workspace number in the config and forcely make some workspace assigned to the second monitor.
So what I am trying to say is the default config and the guides can be refined a little bit more, or newbies like me could run into a lot of confusing behaviors.
