By naming each widget to easily find in the Outline list and addig interaction is a smart way to organize the widgets. As the prototype project gets more complex, I usually have to rename the widgets so they may be separated by each other and can search for them faster. The widget renaming procedure can be done only by manually, but with a long widget list it's a nightmare.
Also there is a search & replace function but it only works on widget text but not on widget names, what is a pity. Also it would be more than great if I can change the widget names only on the selected widgets.
I can't see search and replace on the selected widget name function in the RP9 Beta (188.8.131.5226), so I put a vote on this feature.
