I'm developing a user interface to modify the file hud_options.xml, I didn't have too much imagination and called it R3E HUD Manager. Current features Planned features Display interface for the other options listed in XML (no urge cause these options are already editable in R3E menus). Add images for other MoTeCs (for preview purpose). Improve ergonomics and layout validation. Known issues I've reported the list of things not working as expected here. It's not possible to update the in-game layout while R3E is running cause it reads the HUD file only at startup. While running the game overwrites the HUD file regularly and can modify your layout if it has some "invalid" values. Triple screen layout considers that all 3 screens use the same resolution. If you use another kind of configuration, please let me know. More details At first launch, app backups your current hud_options.xml in the app data directory. So if you modified this file, I suggest you restore the original R3E file before to install the app. If you didn't, you still can edit the "original" HUD file by clicking the gearing button > Open application data directory > and edit the file "hud_options.xml.backup". If the version number at begin of the xml changes, application creates a new backup of this file and move the old backup to a sub-directory "Old Backups". Source code is available here. You can report bugs in this thread or here. Installation You can install the application via this URL. Note that you'll get warnings about installing an untrusted application, I'll check later how to solve this. Application will prompt you at startup when an update is available.
