Reset style

Hi and thanks for your great plugin,

In order to have maximum control over styling, is there any option to get a ‘no-theme’ search form? I mean very raw, minimal code.
Because setting up CSS styles through the plugin options is already nice but lacks some features to perfectly match my existing website design. Also, overwriting an existing search form theme seems really hard considering the number of ID’s and classes used.

Do you have any idea?
Thanks by advance
