• first draft: open the relevant patch files and request confirmation before actually applying.

future steps:

• open a pretty diff view; requires to create a diff, i.e.:
  • apply the patch to a replica of the file,
  • show the diff between the changed replica and the current file
• "peek" instead of opening a new editor
• prettier confirmation dialogue (currently it takes fokus and does not allow browsing the changes without canceling and then having to press apply again)
