I'm not sure about this.
For 1) you can just use right click and Send To.
For 2) I can see the logic behind it and it seems sensible but again, I'm not sure if it is needed, isn't it easy enough to just open a new tab and click on the node you want?
1. of course - but it takes much more clicking than dragging to a tab/playlist I want to send file to!
2. again - it takes not only 2 clicks instead of 1, but also when you open a new tab, the default view that loads in it is "Music" (collection). as my collection is big (ca. 90 000 songs), it takes a few seconds to 'load' it and only then I can pick a playlist I need for that new tab.
Fe. when I'm in (let's say) "Inbox" locked tab and need to go to "new good shit", I need to open a new tab, wait a while for music collection to load in this tab and then choose the playlist I need from the left navigation panel.
Moves = 2, Time = a few seconds
With my idea it goes like this:
I'm in "Inbox" locked tab and need to go to "new good shit", so the only thing I need is clicking on the "new good shit" in the left panel. Locked tab is still opened, you don't have any more mess than with the old method. AND:
Moves = 1, Time = instant!!
So my changes are about economy of clicking - I think the less clocks/moves you need to do sth, the better. Ergonomics is good.
As Charlie Sheen once said "What's not to love?"
I like it as it is. That's the point of a locked tab for me. I can have a library tab and a now playing tab open & locked and that makes it easy for the missus or whoever to use MB and limits what they can mess about with accidentally
-1
But - with my method - it doesn't create more mess. The new tab opened wouldn't be locked one on deafult, so as long as you stay in the unlocked state, clicking on other playlists wouldn't create any new. The scary multiplication of new tabs into infinity wouldn't take place
