Adjusting Width for Groups of Options

[MFMokbel]

Hello,

When dealing with multiple groups of options, the spacing between the option arguments and their corresponding help messages is inconsistent across groups. Is there a way to standardize this spacing for all groups?

Can you show me an example?
It might be a bit of effort since the group help text is output independently. If it's what I think you're referring to then the width depends on the length of the option names in each group.

Precisely, as you mentioned. The problem lies in the varying lengths of long options across different groups, which results in inconsistent width adjustments. I resolved this by standardizing the maximum length across all option groups.

It would be great to have the ability to do it programmatically.

Users should have the ability to have allow automatic consistent width adjustment for all groups.

For example - have Bool·parameter and Vector Parameter appear at same column.
