We are still working on the Joomla update.
It seems you don't have a compatible Joomla template (Fabrik is relying on Joomla's Bootstrap2).

The links are not for sorting but (in a correct template) dropdown options for grouping.
If you want a sortable list column you must enable "Allow ordering" in element settings (List view settings).
The default bootstrap template is Protostar.That's odd, because that is the default template that comes with Joomla.
Yup, that does look like beez3, which is not Bootstrap, but as you say, can be configured to include the Bootstrap JS and CSS. However, I've never actually tried using it. Protostar is our reference template. Personally, when I want something good looking, I use Gantry, which Fabrik works well with (if you install the Fabrik BS3 overrides).

RT have gotten better. They used to have all kinds of nasty issues with not playing well in the shared sandbox, that made accommodating their themes in Fabrik a pain the ass, but they've definitely improved in the last few years.

We often do ask, if it's something we can't figure out from descriptions and screenshots. But we try and exhaust non-invasive options first.

I understand your position, but I also kind of understand Gantry's. Doing tech support in the J! world is very difficult. You are dealing with a wide range of skillsets (skewed towards the low end), language barriers, and a platform where no two client systems are the same, and problems are often down to unique combinations of 3rd party plugins. And it is very often just quicker and easier to jump on someone's system and take a look, than to go through the back and forth on a forum. That said, it shouldn't be the reflexive first thing you do.
Personally I'd say stick with Gantry, as their product is high quality, they have become a reference for a lot of other extensions, and they have legs (they aren't going to disappear).
