Select all/Export

Hi team,

I've been using Cutter for a short while in the field of reverse engineering and I've noticed it seems to be lacking the ability to select all, or export to an external file, like a TXT for instance.

The thought process behind this is to easily copy all the code that appears in the disassembly view and either copy and paste it externally to Cutter for use or analysis elsewhere. Failing that a feature to export the content of a view like Disassembly under the File or Tools menu would really kick up it's versatility for me
