- update editor mention: Helix / $EDITOR instead of NeoVim

 * All file names are encrypted as well and kept in encrypted indices in the same Git repository.
 * The indices are searchable through `fzf`, the fuzzy finder.
 * The Git repository can be synchronized with N remote Git repositories (e.g. to two separate VMs for geo-redundancy).
-* Text entries are edited using NeoVim (with file caching and swapping etc. disabled).
+* Text entries are edited using Helix  (or any other `$EDITOR`)
 * Clipboard support for MacOS and GNOME (Linux).
 * Interactive `geheim` shell support.
 * Can import and export documuments in batches.
