Drag&drop tabs is ultra slow and very unprecise

[Daijobou]

I have 20-40 files open and drag&drop files on position for priority or create groups. But the blue drag&drop line shows only random and drag&drop its a gamble to hit the right position. Most I need many tries. Its need 5-10s to re-position a tab. Thats very bad.
