Customization quesitons

Hi. I am using your plugin here – https://yellowdandelion.com/shop

I have a couple of questions regarding further customizations.? If you could tell me how to achieve these things –?

?I would like to remove the filter button, have the ability to do automatic/ajax filtering? and also keep the filter options on the left hand side the entire time, so it can keep filtering if I want to choose multiple options.? right now when it shows the results it removes the filtering options.? How do I not remove the filter options on the results?
is there a way to put the checkboxes in the filter drop downs in 2 equidistant columns, side by side?
I need a third filter option.? This one is a bilingual yes/no option.? Right now Events are categories, Products are Tags…how do I do a third option if I am already using tags and categories?? can I make a subset of tags?
I need to control the order of the Events and Products in the filter.? is that possible or is the only choice alphabetical, i see ID and numeric in Sort Terms option but i dont see how to set numeric to control it…?
