I appreciate that your trying to help. (Thank you for the lack of snark by-the-way. Many people here assume "if your having a problem or are not enjoying the status quo something is wrong with you.") I've been using LR for QUITE some time and am aware of at least 97% of it's controls and feature set. (Because I use most of them)
However… I have a bit of an issue when it comes to non-image-editing based plug-ins. I am very familiar with the availability however I find them to be either:
1) A general lack of quality. (I just avoid these entirely)
2) Acceptable but broken as soon as a new version of Lightroom comes out. (Which is really bizarre considering their simple non-image editing function.) Other plug-ins that have this issue tend to be uploaders. (And I don't just mean because the service changed their protocols) Although that happens a lot also. I really wish Adobe would push some kind of open standard for uploading to image host services. Between the service changes and keeping up with LR updates I can pretty much flip a coin to determine which week it will work.
For this reason I try to use as few non-commercial and/or "official" third party plug-ins as humanly possible.
However that said… I have not used that particular plug-in (for the reasons stated) Obviously you have so perhaps you can tell me if it suffers from any of the above issues?
(I would expect that "metadata" wouldn't change very much but this is Adobe we're talking about.)
