Override Less Button CSS

Hello,

The plugin is really great and work well, many thanks.

However the “buttons” are really small I would like to enlarge them.

I tried to replace styles with several methods but it doesn’t work (Enqueue script with priority, style to add after wp_head, using of plugin like simple custom css)

It’s planned to release a version with external css sheet ?
Have you got any advise or tips to modify theses styles ?

Thanks in advance,
