Magic Tabs Add On
For refunds, please open a support request using the Get Help link on the marketplace page.
For developing a theme specific template the easiest starting point is one of the self contained starter templates. Just copy and rename the starter into /application/blocks/jl_magic_tabs/templates/... (as you would for any custom block template). Within the templates there are excessive comments detailing what/where to make changes, such as css styles for tab and icon colours.
Magic Tabs also integrates with Button Designer, so buttons created with Button Designer can be used for tabs.
Addressing your question about content revealing on hover, that is a fundamentally non-tab behaviour. Hover is not available on touch devices. Tabs or accordions open with a click (or touch) event so as to not exclude more than 50% of visitors for most web sites.
As I noted previously, for support of any marketplace addon or theme, please use the 'Get Help' link on the associated marketplace page. The 'Block Requests' forum is for help with creating new blocks, not support of marketplace blocks.
If you open a support request through the 'Get Help' link on the Magic Tabs marketplace page, there is a section for pasting your environment details - including theme - which will facilitate providing more specific assistance.
