Hi!
1. I don’t know if the isotope script supports rtl layouts to be honest. I will check with the developer to see if there is anything we can do about that.
Until then, this custom CSs might help, I’m not sure:
[html].resdrg .asp_isotopic_item {
position: static !important;
float: right;
margin-right: 10px !important;
}[/html]
2. The color is inherited from the theme, to control it, you might need a custom CSS for this as well:
[html].searchsettings fieldset .label {
color: red;
}[/html]
