Minor UIX improvements

[mghenciu]

What problem does this address?

I did some exploratory testing and found a few minor UIX challenges that should be easy to fix, while hopefully decrease the UX friction and improve the product overall.

What is your proposed solution?

• There's a Green Checkbox for each chart, that I assume tells the users that everything is ok with it. But I think we can improve the text, since right now 'A-OK!' doesn't tell a lot to an user:
  

Depending on what that Checkbox means, we can have it be more specific.

• when copying the Shortcode in the Charts grid view, we are using an native alert() method. This adds more friction since users have to click ok each time. I think it would make more sense to use a Native WP toast, or another type of toast that doesn't require user input.

• Do not close the Edit/Create modal when clicking outside.
  Since clicking outside the Modal is more like an accidental situation we want to avoid, so users don't loose their work - I suggest we add a close Icon in the Top-Right corner (which will be used for closing the modal), and disable the close when click outside.

• I suggest that the Get Visualizer Pro link from the Sidebar - open in a New Tab. Currently it opens in the same tab.

• have the option to change the background color. Let's say as a user, I want to creat charts that work in Dark mode. This is an example. This should be easy if we just define a color var and expose it in the front-end.

Will this feature require documentation? (Optional)

No.
