It would be nice to be able to use multiple libraries for different events/venues. I know you can sort by Genre, but for example, a Latin event might use multiple genres of latin music, while a Ballroom event might use a different set - some Latin as well as others. It would be great to be able to only load the music I want for each.

Not sure of how things are internally, for example if an internal database is used, but I would also think that that could conceivably save people memory space if they don't have to load their entire library onto memory.

This is already supported by the Mixxx command line.

You can start mixxx using
mixxx --settingsPath PATH
where PATH is the alternative library DB location.

Unfortunately this is not easy to discover.
So we can keep this bug open for accessing this feature from GUI.

IMHO a full featured version of this is:

Isn't this use case covered by crates and the crate filter ( #1263 )? Also, the library redesign branch ( #1117 ) adds a search filter for the library directory.

If a user wants for example two kind or star ratings, it is not covered.

What if implement some kind of profiles in options, like in games. That will implement the feature about "rehearsal mode", different libraries and other. Also you can take someone's computer, load your profile (with settings too, optional path to music) and go on DJing.

Hi Onur thank you for picking this up.
Do you need a helping hand?

Could you outline what you are planning?
This will ensure your work is finally mergeable.

Hi Daniel,

Sorry for the late response. I was a bit busy. I want to start working on Mixxx. However, I don't know the development environment very well. So I have chosen this issue to warm up since it has no strict deadline.

I have set a development environment firstly. As I see you are using Qt 4.x for example. In my environment the Qt 5.x version is set. When I prepare and ready to edit the codes I will inform you.

Cool. Thank you. Which IDE you will use on which Os?
This is a good start to read:

I'm using Qt Creator or Clion depending on purpose on Mac OS. For such case it would be affect to develop on Mac OS.

This is quite a large and complicated task for a first contribution. Please provide more details about your plans before you start implementing this. How do you intend to expose this in the GUI? We have a major redesign of the library GUI in progress ( #1117 ). It would probably be best to start working from that branch.

I have checked the branch so I can pick a new issue. Simple is better you're right. However I'll do this on Saturday.

I'm afraid this is not a one day task. Could you make a mockup of how you intend to integrate this into the GUI?

I mean I can pick one easy bug for the first time. I should check all the easy-to-handle bugs firstly. I can only do this on Saturday.
