Hey,
I have some problems/improvements:
OK, but you have neglected the first rule of all problem reports, which is to describe WHAT it is you have problems with.
You only describe the problems themselves, saying nothing about the hardware and software configuration where they appear.
In the partial replies further below I will emphasize some of the things we need to know more about, relevant to each.
Here I will specify some of the things that should be included with EVERY report on RasPlex.
What is your RPi type: RPi1 or RPi2 ? (Here RPi1 includes both "RPi model B" and "RPi model B+"
The difference is crucial to everything involving speed, bitrate capacity and GUI fluency.
If your type is RPi1, is it overclocked or not ?
And if overclocked, what are the parameters for it used in "config.txt" ?
What is your connection type: Wired or Wireless ?
The difference is crucial to everything involving PMS transfers, both for playback and GUI graphics.
Some of your questions seem related less to RasPlex than to "Plex Media Server" (aka: PMS) or official "Plex Home Theater" (aka: PHT).
So to request changes for some of these things you need to post in other subforums, dedicated to PMS and 'official' PHT.
1. Speed
I have the problem that the covers from my movies and tv shows are loading very slow. And the "On Deck" animation for movies and the other stuff are also very slow. I don't know if you guys can fix that, but if you can do that you are great!
Have you used the sidemenu command "Control Precaching" to ensure that you have local copies of all posters for RasPlex ?
This affects GUI speed, as it allows local access to posters for listings rather than fetching them from PMS each time.
The first time used the precaching operation can take a long time (depends on your library size),
but thereafter you don't need to do it very often (only when you've added a lot of new content).
2. Interface
The actuall Interface are great but i think the apps for xbox, roku or the other plex clients are better (thats my opinon).
'apps' are no part of RasPlex. The online services it can access depend on the 'channels' installed for your PMS.
You're probably referring to non-Plex apps/channels used in those other media players in addition to their Plex support.
If you're unhappy about the "Channels" available for PMS, please bring that issue up in a subforum dedicated to PMS.
In this particular subforum we deal ONLY with issues related to the RasPlex implementation of PHT.
3. Customize "Home Site"
I think it should be also awesom if I can choose the the libaries or topics in the 'Home Site'.
The appearance of the GUI's main menu, like all GUI rendering, is intended to be an exact copy of that in 'official' PHT.
There will be no changes to the GUI, except for such features required by the RPi hardware or the underlying OpenELEC system.
(Like the "Control Precaching" and "System Settings" commands in the side menu.)
That said, you can install custom skins for RasPlex, just as you can do for 'official' PHT, to modify many aspects of the GUI.
This includes some re-modelling of the main menu in some skins, though the extent differs (possibly not what you wanted).
And now a question:
Can I set a "first" language? I want to set a primar language for all media.
Not in the RasPlex GUI. Such a feature does not exist in 'official' PHT, and thus not in RasPlex either.
But like hthighway said, there is a setting for preferred tracks in PMS, which will affect ALL clients, not just PHT/RasPlex.
When a movie contains multiple audio tracks the playback should use the one flagged as default in the file or by PMS,
unless you override that choice yourself either in the pre-play screen or in the OSD menu opened during playback.
Individual choices made in the Plex/Web media manager also seem to affect/override file defaults for PHT/RasPlex,
but the choices made in the PHT/RasPlex GUI can always override either default.
