Another thing I forgot to mention is when we press the Preview mode the preview use the full screen instead the part of the screen we are currently building (desktop)
I notice a bug, if I all the time resize the preview screen at some point that get the feeling as been locked the mouse to the resize button and not able to edit the project, to start edit again I need going to dashboard and select the project again
I don't notice either of these issues. Are you using a Chrome/Chromium-based browser? I had some issues using other browsers with WebStudio, and switching to Brave (Chromium-based) resolved them
