I have a problem with the UIbuilder

[Controller]

and what can i do to work with this program ? the uibuilder is making so many changes. Takes lot of time to find and undo them. Cause if keep the changes of the uibuilder the xml file is no longer working.
Is that really the way the uibuilder works ? ****ing up the xmls with lots of unwanted stuff til the files are no longer working ?
I remember last year i was editing some files with no problem. But now everything seems to be broken.
Is this how you guys work with the uibuilder ? work on some xmls and next step is to find all the changes the uibuilder made and undo them ?
