For your initial question you should learn to use the different Object Modes (see the manual). 

  

  For example to nudge all the objects on the right of one object, you should select Link All Tracks, select only the first object and nudge it 

  

  To nudge all the object on the after a selected object but only on one track, use Link on Track 

  

  etc. 

  

  I switch a lot between these different modes when mixing for drama. 

  

  You should note that only the Link all Tracks mode move the markers on and next to a moved object. 

  

    

  

    

  

By selecting several tracks in the mixer the aux levels will be changed relatively to each other, if you add 3 dB to one of the track the rest will add 3 dB to the current value. 

  

  To change several aux to a specific value use ctrl + left click to select the aux level controls and all will be set to the same value you enter for one of them.

What is did not like originally is a muddy bass extending to much to mids. 
  As i found out HTC bundled bassboost audio effect , which is responsible for enormous bass extension to mids.
  The bassboost is always on , even you torn-off Dolby in settings.
   
  So if your phone is rooted you may try to delete /vendor/lib/audiofx/libbassboost.so and vendor/lib64/audiofx/libbassboost.so to get more clear sound.
  The same effect can be achieved by installing some mods like Viper4Android (in Normal mode) or AINUR NERO as they are bypassing or completely deleting  vendor's audio effects.

when using my sensitive earphones, standard Poweramp produces a noticable background hiss that disappears when Hi-Res is enabled.
