Simple one... add a content editor web part and add the following code:
<style>
.ms-menubuttoninactivehover{
display: none;
}
.ms-separator{
display: none;
}
.ms-splitbuttondropdown{
display: none;
}
.ms-viewselector{
display: none;
}
.ms-listheaderlabel{
display: none;
}
</style>
You'll notice that some of those buttons disappear.
