Create New or Modify Rounded Template?

Because our website template is a three column one with the main block 610px wide, I have to modify the cbsubs rounded template.

I have done this by modifying components\com_comprofiler\plugin\user\plug_cbpaidsubscriptions\templates\rounded\cbpaidsubscriptions.css

However, I am concerned that when you update CBSubs next, if I upgrade, the rounded template will overwrite my modifications.

You talk in the manual about users creating their own template based on rounded template, but I can't see any detail how to do this.

Do I copy the rounded folder and modify any files in that folder? Please advise. If you release a new cbplug_cbsubstemplate_rounded-E.zip, how will I know what to change to keep up-to-date?

Also can you advise me about the .png files? If I halve the horizontal size of the currentplan_bg.png image using Adobe Photoshop, for example, will I be able to halve the widths and background-positions in cbpaidsubscriptions.css widths?
You talk in your promotional material about "Rounded template improvements (psd layer, new red icon, etc.)" - is the psd available to users?

Thanks

As the rounded template is installable you'd simply copy it, alter its names, alt its xml, and then install it. This would give you a new custom copy of the template. You'll basically replace "round" with "round2" for example (edit PHP/XML filenames as well).

If you release a new cbplug_cbsubstemplate_rounded-E.zip, how will I know what to change to keep up-to-date?

You'll need to use a DIFF program such as Winmerge, etc.. to diff the files and see what's different between them.

Also can you advise me about the .png files? If I halve the horizontal size of the currentplan_bg.png image using Adobe Photoshop, for example, will I be able to halve the widths and background-positions in cbpaidsubscriptions.css widths?

No idea as I did not develop the template. It's likely just reducing its width will do the trick.

Yes, in the images folder of the rounded template.
