Thanks Jim - I will get on to that.
I've tried to find a contact name for J River to contact them about this but the only thing I've found is the name of the VP of marketing - does anyone know who I should refer a complaint to?
JimH is the CEO and Matt is one of the software engineers. So you have an open dialog already.
I assume that Panes is a new feature too? I've not seen it before or at least never had it as part of my view previously.
The "Panes" feature is not a new thing. I think it was introduced in MC 9.1.
After re-reading this thread I think you miss the previous "Library Browser" function.
Everything it had and a lot more is included in MC11.1. The functions are combined in the standard file browser.
Only thing that is not included is the graphical "tab buttons" row on the top of the view. The buttons are now textual, because that makes them more adjustable. You can add your own custom tabs by editing the current view scheme. Previously it had only the pregonfigured Generes/Artists/Albums/Files tabs. JRiver is rewriting the program help file and I hope the new system will be explained well.
Please try to read the few posts in the threads I linked that especially explain the changes. The threads contain a lot of posts that do not help you, but you could try to skip those posts.
Since the MC11.1 upgrade is free for MC11.0 customers and no one is obligated to upgrade I don't think there is much to complain about, but I sincerely hope that you can find out how the new system works before making a decision (you can always install MC11.0 back). In my opinion the new browsing system is the best improvement in MC11.1.
