I have the most current one. (version 1.8.6, build 131129 according to the admin screen) I still don't see an interface for the new social media buttons option (I assume because that a fairly new thing) I also don't see the option for the main image corner radius.

Here are a couple things I noticed and one suggestion:
On mobile devices when you have a caption it gets cut off on the bottom of a device (Image here - ttp://i58.tinypic.com/9sa238.png) and in thumbnail view the title of the gallery is visible even tho' it's turned off in desktop versions. (This was also an issue I had with SV) Also the home icon doesn't appear when it's just the thumbnails on a mobile device. You have to view one of the actual images to see it. (Don't know if that's on purpose)

Also, I know this is not the place for this I thought I would mention it: With svmanager have you guys considered having tooltips over the options to give a simple brief description of what the options do when you hover over them with the mouse? Things like "show in small screen mode". No idea what that means without having to stop what I am doing and look thru the documentation. If it had a simple blurb over it (Like how photoshop does with it's tools etc) it would expedite people's workflow I think.
