As the RTL is now moving into more and more HTML5 based features, the old HTML4 miniblink browser has reached the end of it's capacity.
I will be removing this from our codebase since it quite frankly offers no real benefit over opening a project in the system default browser (Chrome, Firefox or Edge).
The only benefit an embedded browser can have, is that we can design it so that it would fit 1:1 layout of mobile applications and various display sizes for different phones. However, this is something that modern browser now support out of the box when you open the browser development tools, so the need for this type of embedded browser has become less and less.
I move to remove Miniblink completely, and instead stick to the system browser when running your applications. When doing a rebuild of changes, you can then just refresh the browser to see the changes - leaving the devtools open.
