Hi there, lovely skin!
Thank you
I am wondering how I might do 2 things:
1. When I am using folders, only the folder menu appears on the home page. Is there any way I can display an image on this home page as well?
If you put an image in your root folder (the folder that's containing the subfolders) this image will be displayed on the home page.
2. Once I click on a folder, the menu with the folder list dissappears. Is there any way to make the menu with the folder names stay on the top of the screen?
Currently no. If you open up a page for a folder you will only see the subfolders (and of course the images) of that folder. You should however see a "breadcrumb" navigation in the top so you should be able to click the root folder's name to get back to the home page.
Or was this skin not really intended to be used with sub folders?
It has support for sub folders but to be honest with you I haven't really put that much energy into folder handling (except for getting the breadcrumb navigation to work, which was kind of complicated). I actually plan to focus on better folder support for the next version so any suggestions are welcome.
