The GUI still should be fixed on cutter side.

But maybe also automatically generated flag names for strings should limited on rizin side. I don't see the point in including x KB of xml file as a flag name for string. Possibly prefixed with a length and address when the length limit kicks in to help disambiguate them. That doesn't mean all flag names need to be limited, only automatically generated ones, user should still be allowed to set the name to whatever they want. For now also not suggesting anything for function or other symbol flags, since those are more likely to have somewhat reasonable size, mangled template names can be a bit crazy but nowhere near as bad as giant XML or other textfiles embedded as strings.
