A full function linux control point?

[Pastim]

I've done some tests. Not that many because I've been tied up with other stuff. However, a few comments, in no particular order:

1. It seems to ignore items at lower levels preceded by >>, when selecting container at a higher level (I believe simoncn has discussed this with you) - Good
2. The layout when it gets down to track level leaves a little to be desired - see screen shot attached. The 1st track is misaligned.
3. A 'play all' (ie all tracks shown), or 'play from this track on' (ie sequentially down the list of tracks shown) option would be really useful when right clicking on tracks
4. When selecting a container that has multiple items at a lower level with the possibility of duplicates, it is very slow. It took 2.5 minutes to find 35 tracks for one work (La Boheme) by one conductor (selecting at this level) for which there are 2 albums below. When selecting another conductor for the same work with only 1 album, it was almost instant. I believe you rather feaared this might be the case.
5. However, I haven't yet caught it returning duplicates
6. A nice-to-have would be to be able to change the track selection listing column widths, and/or even the column contents when tracks are being displayed (this is probably a lot to ask). To be clear, the playlist is fine, it's the selection list to the right I'm referring to.
