QtScript service issues

[Be]

I have found what triggers the first bug and figured out a work around.
Level 2 items must have playableUrl set to an empty string. That does
not make sense to me and I think indicates a bug in the scripting API.

Regarding the last issue, it would be helpful if scripts could disable
Amarok's sorting and specify their own sorting mechanisms. With this
script, SoundCloud returns the most relevant search results first and
thus the script inserts the items this way. Having the search results
sorted alphabetically by Amarok is inconvenient.

I've noticed that sometimes SoundCloud returns different results for the
exact same query. I don't know what's going on at their end.

I added a number of features since the previous email. The script now
shows users' favorites, who they follow, who follows them, and what
groups they belong to. Groups can now be searched by putting 'group ' at
the beginning of the search term. I think searching for groups with
'group: ' at the beginning would be more intuitive, but strangely, any
word with a colon in it is not passed to the script. Searching for a
group shows its tracks, members, moderators, and contributors.

I kinda figured out a hack to make the tree interactive and navigate
between users and groups. By making the playableUrl of listed users and
groups the terms that could be used to search for them, they can be
dragged into the search bar. This hack allows invalid "tracks" to be
dragged into Amarok's playlist though. More importantly, when doing
this, the tree will not populate. Clearing the search bar and searching
for the exact same query works though. This happens whether dragging &
dropping an item from the tree or quickly typing a different search term
in the box.
