Version 146 of Hook’s app-integration scripts is now available with the following support.

The following is is already packaged in Hook 2.2:

- [RStudio](https://rstudio.com/) - open source & professional software for data science teams
- [FreeMind](http://freemind.sourceforge.net/wiki/index.php/Main_Page) – free mind mapping software
- [Freeplane](https://www.freeplane.org/wiki/index.php/Home) – free mind mapping and knowledge management software ([Freeplane is a fork of FreeMind](https://www.freeplane.org/wiki/index.php/Relationship_to_FreeMind))

We have added support for a couple of additional email clients. However, we cannot recommend these apps because the email IDs or URLs they expose are **not** compliant with [RFC 5322 - Internet Message Format](https://tools.ietf.org/html/rfc5322#section-3.6.4). This is the same problem that the Outlook app has. If the email’s ID is _not_ RFC compliant, it cannot be shared with others and is not guaranteed to work on different Macs - even of the same user.

- Spark email app by Readdle.
- [Mailplane - Gmail client app](https://mailplaneapp.com/).

We recommend using email software from which you can copy [RFC 5322 - Internet Message Format](https://tools.ietf.org/html/rfc5322#section-3.6.4) compliant IDs. Please see [What Mac Apps Work with Hook? – Hook](https://hookproductivity.com/what-mac-apps-are-compatible-with-hook-app).
