Add a view like “output view” where we can see XAML as plain text and edit from there.
When you are programing UIPath works very slow sometimes and did not works properly when doing some basic programming in assign box. For example crash a lot when you use multiple lines in a property.
In other not technical IDE they add the option to read and edit de XAML file which helps a lot when you want to edit a lot of boxes at the same time. For example you can replace all name variables from there, change some basic text, and also may help to edit fast name of activities box.
