1. If I start playing a tune from Hydrogen with Qtractor being in Full Transport mode, first second of the tune in Qtractor is silent.
Just thought about this and maybe you're right, this can happen and probably much more evident if your JACK buffer size is greater than, say 128 frames? Please check if this makes any sense, whether it gets worse as Qtractor being slower transport sync, in direct proportion to JACK period cycle (ie. buffer size) ?
[UPDATE: Wait, this only happens when you start rolling from the outside and Qtractor play-head is exactly at the beginning zero position, right?]
2. Piano roll has to be an active window when it gets opened.
Yeah, you know what? that annoys me too :) to date I've been trying to fix that, too many times already, but somehow I always end scrapping all efforts as some waste of time and move along with other things, being one of those is clicking on the piano-roll window and get over it -- uber-procrastination in all its glory ;) Ok. I'll try again but this time pray for not end using some brute-force approach and break something else :)
[UPDATE: If you turn off View/Options.../Display/"Keep tool windows always on top" you'll get it working as you ask, but then, you'll be trading for some other side-effects which might annoy you even more, like the Mixer, Connections and Plugins windows getting cluttered out of sight way too easily :)]
3. In piano roll can right click of a mouse on empty space deselect all notes?
Hell, no, that should not happen! Right-clicking should invoke the context menu. It is Left-clicking on empty spaces that should de-select all notes, unless you're pressing either Shift or Ctrl keyboard modifier.
4. In piano roll selection mode is not effective as it could've been.
Speaking of which, re. Shift and Ctrl modifiers. Shift does inclusive addition as it seems to do exactly as you ask. On the other hand, Ctrl works like you say, toggling notes as doing like an exclusive-or (XOR).
5. Freezing tracks - writing from one qtractor into another resulted in delay.
Ouch! Weird things can really happen if you run more than one instance of Qtractor, specially if both are set to be JACK transport masters. Anyway, the multi-instance possibility is something that I won't recommend in any circumstance. In fact, until very recently, multi-instance was indeed forbidden by design, but support for JACK session protocol had to dig a hole on that :) FWIW, please, restrain yourself to run one and only one Qtractor instance at any given session, please. Weird things can happen otherwise ;)
