Your Companion application is a great tool for editing documents attached to pages in Confluence. However even though there is a significant number of users with Linux as their primary desktop OS you only provide Companion for Windows and MacOS.

There was a suggestion for a Linux version some time ago, https://jira.atlassian.com/browse/CONFSERVER-56399 but this is closed with a Won't fix status. The clossing message in the comments is upright ridicolous. It tells us you will not make a linux version and then suggest that we install Companion for editing douments, which is not available for linux. Not very logical...
