Reputation isn't handled well with this. Is there some way to include it with the rest of the fields?

Rep Power is included with the rest of the fields. And it can be moved around without any problems.

Have any update for work on 4.1.10?

Sure, I've had the update running on a site that runs 4.1.10 for a while now to be sure there aren't any problems.

The update was released on my site today. It will follow here next week.

Thank you for this mod.

Could you imagine to add an option permitting to select if by default the postbit info is collapsed or not?

Not sure why (haven't really looked into it yet) but this mod isn't working for me OOTB.

-EDIT-

Just so I'm clear, it's not just modified styles, but all styles.

Check for mods that force the use of postbit_legacy..

I saw that after I posted. Apologies. It was the DBTech Thanks/Like mod. :(

Love the idea, but when using it with the default template and horizontal (new) postbit, it removes everything but the user name and member level. All the fields on the right side disappear when it is enabled.

Could you post a screenshot of what you're talking about?

The attached screenshot is how it should look using the default postbit template. It shows the postbit info collapsed and expanded.

The postbit info should be hidden when it is collapsed. On some site, the postbit info is huge and takes up a lot of room. This mod hides it so it doesn't take up so much room.
