I wanted a simple web interface to act as a nice overview/front page for my XBMC HTPC. I couldn't find anything that suited my requirements so I created something myself.
You can find more information and setup instructions on the project homepage.
There is now also an official forum which is your best bet for support, feature requests and bug reports.
In addition, there's also a thread on the XBMC forums.
Customisable applications module providing quick access to your web interfaces (e.g. SABnzb+, SickBeard, or whatever else you want to link to).
Recently added episodes/movies/albums modules - click an episode or movie to play it in XBMC.
Media library browser - browse your entire movie and TV library, and click to play in XBMC. Queue items to play after.
Control multiple XBMC servers - do you have an XBMC server in both the living room and bedroom? Switch between the two instantly and control them using Maraschino. Send notification messages to them remotely!
SABnzbd+ and NZBGet modules manage your nzb queue from within Maraschino - they appear when something is downloading and hide again when finished - shows you what is currently downloading, speed, time/MB remaining, and a progress bar. Control (pause, resume, speed limit) your downloads.
Usenet search - search Usenet and add files directly to SABnzbd+ with the click of a button.
Currently playing bar with play/pause/stop/volume controls, and a clickable seek bar.
trakt.tv shouts module which shows you what people are saying about the episode or movie that you're watching, and allows you to add your own shouts (requires a free trakt.tv account).
trakt.tv plus module - see what your friends are watching, and view personalised TV and movie recommendations based on your viewing history.
Sickbeard module which allows you to browse upcoming episodes and manage Sickbeard directly from Maraschino (add new shows, search for episodes, etc.).
CouchPotato module which allows you to browse upcoming movies and manage CouchPotato directly from Maraschino (add new movies, etc.).
Headphones module which allows you to browse upcoming albums and manage Headphones directly from Maraschino (add new artists, search for albums, etc.).
Disk space module showing you used/remaining space on your various drives.
uTorrent and Transmission modules for the torrent users among you.
Weather module for your local city, because why not!
Full-screen background image which changes to the fanart of what you're currently watching (optional, can be turned off - but looks kinda pretty)
Customisable from within the application itself - choose how many columns you want, add new modules, rearrange them using drag-and-drop, and modify their settings without touching any settings files!
Uses Flask and some other awesome technologies (SQL-Alchemy, LESS CSS) but you don't need to know about that if you don't want to.
It is released under the MIT License, which can be found here.
If your HTPC is an ice cream sundae then Maraschino is the cherry on top.
