New keywords:
- Wait For Function (polls for a javascript function or expression to return a true value)
- Wait For Request and Wait For Response

New keywords:
- http
- executes fetch with page.evaluate
- support all common HTTP methods, GET, POST, PUT, PATCH, DELETE and HEAD
- if request body can be converted to JSON, it will automatically add content-type header
- if response body can be converted to JSON, it will be returned as a Python dict.
- Get Style (supports assertions)
- Get Element (returns an element handle that can be used as a selector)

Other improvements:

New keywords:
- Set Viewport Size and Get Viewport Size
- `Switch Browser`, `Switch Context`, renamed `Switch Active Page` to `Switch Page`
- `Get Browser Catalog` to list all open browsers, contexts and pages
- `Close All Browsers`

Improvements:
- `Create Browser` and `Create Context` have options in type signature and parse them correctly
- We're looking into hiding optional parameters from LSP autocompletion but it might take some time
- Better activation of new browsers / contexts pages when using `Switch Browser` / `Switch Context`
- More stable Browser aliases when closing Browsers

Fixed invalid parameters for opening the browser.

New keywords:
- `New Browser`, `New Context` and `New Page` to create playwright objects representing multiple browser instances, browser profiles (contexts) or tabs (pages)
- `Switch Context` and `Switch Page` to switch between open pages
- `Switch Browser` has been added but is unreliable and not recommended for use yet
- `Get Element Count`- gets amount of elements matching `selector` and supports assertion syntax

Other features:
- \>\>\> selector syntax for piercing frames
- Better error messages

New keywords:
- Select Options and Deselect Options (Keywords to manipulate \<select\> element options)
- Wait For Elements State
- Execute Javascript On Page
- Get Page State

The two latter keywords were created to help with frontend JS integration. We will be adding more syntactic sugar and documentation in the near future.
