you didn't include TbExtendedFilter in version 1.0.4. I was really looking forward to it... bummer!
An observation: Shouldn't the input for TbSelect2 have round corners, too?
Another question: Is there any way to omit the highlighting of errors in forms? It would be quite useful if there were the following boolean options: highlightErrorsOnLabels, highlightErrorsOnInputs, highlightErrorsOnHelpers. Of course the default is true. When set to false the element will not be highlighted red if there is any error.
Edit: The original option "errorMessageCssClass" gets overwritten in TbActiveForm and it would only effect the help-block (not the label and input) hence the overwrite.
Yeah, I am truly sorry for not including TbExtendedFilter on version 1.0.4, but I would like to write proper documentation for such widget, if not used properly, then it could lead into issues so I cannot just dropped there and I do not have much time nowadays really... very, very busy.
About your ideas, I would be more than please to check your proposals through a Pull Request in the github repository... looks like a nice one.
Best regards and I promise to include TbExtendedFilter in version 1.0.5. The work in progress branch should have it by today (no docs yet)
