NetBeans 8.1: Hints Not Updating Dynamically and Go To Source Not Working

I just started using NetBeans and have discovered several issues that look like bugs. I came from Visual Studio, so chose an IDE that did similar type of error/warning checking and suggesting of what to do to fix it.

So, in NetBeans, I create a new HTML5/JavaScript project with the "Initializr:Bootstrap" template. Let's take the pre-made Index.html in this template as an example.

It shows an error on line 33 (a button tag), and a yellow lightbulb on the left side gives a range of so called "hints" to solve the issue. Those can be clicked to automatically implement the fix. In my example-case it includes suggestions such as Declare aria-expanded as attribute of element button and Create rule .collapsed in stylesheet css/bootstrap.min.css, plus many others.

These are my questions / issues:

1. When I click on one of the suggested fixes, the program applies the fix, but I have no way to check what was actually done if the change happened in another file. For example, if I click on the hint to create a rule in a separate CSS file, it does not always open up that CSS file to show the change. Also no way to undo if the change was to a separate file

2. Let's say I am lucky and find out what change was actually done by the program in question 1, and I go ahead and undo that change manually. The menu does not update dynamically to now show the hint again. Once a hint is implemented, it seems to be gone from the hints menu forever

3. If I go to the Navigator window, expand the CSS/Classes list, and click Go to Source on say .btn-success, it does not take you to the source. It should here open the css file i assume, and show where the class is defined, however nothing happens

4. If you try to Format CSS files, you will immediately see that it does not add indentation / line breaks. So if all your CSS code was on one line, and you try to Format by clicking Alt-Shift-F or going to Source-->Format, nothing happens.

Am I missing something here or are the above simply bugs NetBeans has yet to fix?

Thanks in advance.
