We just added the ability to edit more than one element at once in the editor, which will help maintaining larger apps. For instance, to change 3 buttons and make them follow the same style, have the same width, etc.
You can do this by pressing ‘Shift’ in the editor and clicking on several elements. You can also do this from the Search Palette. You’ll see a button above the search results and you’ll be able to modify the elements.
One thing to note is that, for safety measures, you’ll have to click ‘Apply changes’ to make the changes real. And you can undo/redo changes as usual.
