Suggestions:

• Default is 'private' or 'public' home
• Only turn on selected module (sethome/home/delhome)
• Alias of command (/home delete abc == /delhome abc)

• Default is 'private' or 'public' home
• Alias of command (/home delete abc == /delhome abc)

I think these are really good ideas.

• Only turn on selected module (sethome/home/delhome)

Please tell me more about this.

The module means sub-commands, such as I only turn on 'set home' and 'home', so 'invite' and 'delete home' and so on will not be able to use, even with the correct permission set. The reason I am raising this, is because it will become useless in my server's gamemode, since players is not allowed to use such feature.

I think that it is possible by setting permissions individually.
For example, for general users only set homes.command and homes.command.set.
