Errors are normal for Arch Linux users, that’s everyday food, we will always learn new things, read some documentation, read write-ups, compile some configurations, understand the structure, learn some programming languages, and so on.

If there are empty gaps of desktop space outside terminal windows, it is likely due to the terminal’s font size. Either adjust the size until finding the ideal scale that closes the gap, or toggle resizehints to 0 in config.h.
