Can I add an attribute to an element?

Dear Nicepage, I think it would make a lot of sense and save a lot of work if it was an option to lock width and height. Then I dont have to go in and clean up the mess and "Reset changes for this...

target attribute in hyperlinks may be very useful name attribute for elements too

It would be great if you could add an option to add attributes to elements, both standard ones(like onclick, on...) and non-standard ones(like data- attributes). Thanks in advance
