Hi!
Thank you for the great review, I really appreciate that.
Well, if you dynamically load the checkboxes like so:
[code]
{get_values}
[/code]
…then by default they will be unchecked, and with this:
[code]
{get_values checked}
[/code]
then all of them will be checked. For individual values, if there is a double star after the line, then that value is checked, otherwise unchecked:
[code]
unchecked||This box is uncheced
checked||This box is checked**
[/code]
Select all option is not yet available, although I am pretty sure that should have been implemented by now. I will make sure to add that feature to the upcoming release.
More details can be found here: Custom field filters documentation

Indeed, that is not possible, at least not yet. However, you can create multiple search instances, all with different configurations. Perhaps, if you need a bit different layout for each dimension, you could possibly make a search bar for each. You can even duplicate the search bars, once you have one up and working, to make things faster.
I don’t think that there is a better solution right now.
