I'm trying out PowerShell 7.6.0-preview.5, and it's fantastic. ❤️

Here are some features I particularly like:

• Use parameter HelpMessage for tool tip completion #25108

This change also affects the Language Server, enabling parameter descriptions to be displayed.

Currently, even for built-in commands, only some parameters have this feature enabled.
I'd love to see these descriptions available for all parameters in the future.

• Support registering a cover-all completer for native commands #25230

In PowerShell, external command completion required registering completion codes for each individual command.
However, this change enables the configuration of comprehensive completion codes.
I am currently developing a PowerShell module that dynamically executes scripts placed in the completions directory, similar to bash, zsh, and fish, to provide completion. (Windows is also supported, of course.)
