Is there a way to bribe (oops, I mean sponsor) LO developers to add new features?

There are a few features that I would really like to have added to LO Writer, all of which I believe have been requested by at least one other user in the past, and I’d even be willing to bribe/sponsor/pay an official developer to implement them. Is there any way I can go about doing this? Some of the features I have in mind:

• Optical margin alignment
• The ability to export to PDF/X formats
• Improved hyphenation (I can go into more detail about this later)

Have you looked at Professional Support | LibreOffice - Free and private office suite - Based on OpenOffice - Compatible with Microsoft ?

Normally, I would suggest enhancement requests, How to Report Bugs in LibreOffice - The Document Foundation Wiki but for the large changes it would require considerable effort. For pdf/x support I think that colour management would be needed too. There have been a number of changes to hyphenation recently as documented in the release notes, e.g. ReleaseNotes/25.8 - The Document Foundation Wiki

Have you considered Scribus? That has colour management and I think that it can export to pdf/x

Yes they can. I’m using the feature.

I found a thread for manual conversion, but I don’t think this will suffice to use it often.

But there is also mentioned to use ghostscript

It may be a realistic option to create an extension to use ghostscript. But one will always need additional configuration like an ICC-profile fitting the output device. All embedded Images will need to have a profile or be sRGB. …
