Update: Mini-Slide 2.0 supports templating!

To get the right look and feel for the output of the Mini-Slides Plugin, I use following css:

.dprx_minislides {
	border: 5px solid #eee;
	background: #eee;
}

#sidebar .dprx_minislides {
	width: 90%;
}

#sidebar .dprx_minislides_nav {
	font:12px Georgia, "Times New Roman" Georgia Times serif;
	font-weight: bold;
}

#content .dprx_minislides {
	width: 130px;
}

.dprx_minislides_nav {
	margin-bottom: 15px;
}

.dprx_minislides_nav a {
	padding-left: 3px;
}

By the way: you can have both: The template tag e.g. within the sidebar.php:

if (is_single() && function_exists("dprx_display_minislides")) {
		dprx_display_minislides();
}

as well as the [ minislides ] tag within the post itself. The Plugin detects if there hase allready been an output for that set of Images and omits another Mini-Slides. Since my sidebar is a left-hand one, the Mini-Slides are loaded within sidebar.php template before the single.php template.
