The HP information is included in the info of each module. It's probably the only value that you cannot escape using when adding a new module.

You can see it underneath the blah blah included in most modules. It's located below the power info (if available), as a tag.

Additionaly, it is included when looking at the modules using the Module Finder.

Last, but not least, you can find it when using the Popover option and while you hover your mouse over a module.

Oh it's as a tag, saw it. Always thought it is written altogether with the current and module depth values. Big thanks!
