This is my last "feature request" ...
I'm thinking of a function to do some basic byte manipulation. Something like rot13(), rotXY(), xor() or similar on a marked selection. Checksums like md5(), sha() are even implemented yet. But in my case it could be useful, if the new contend ist changed in original view.
I'm not shure if this is a feature HxD would implement. If not, maybe somebody has a tip for another software, which can be used for such manipulations.
