(1.2.3.pre-2.apk) Pause button not properly showing up (added logfile) about voice HOT 2 CLOSED

(1.2.3.pre-2.apk) on MotoG 4.4.3
Suggestion : Relating to the app behavior at Notification bar, with #6
Notification bar could have consistent play control.

Of course, it's matter of preference, but I've compared behaviors of other audio player apps I use at Notification bar

Vanila Music

VLC

----As one sees, in screenshot[1], 3 apps all act differently at Notification bar

Vanila Music
3 buttons
"Play" button (by tapping, turns to "Pause" button, tap again, resumes)
"Next" button
"Close" button
with 5 behaviors (Play-Pause-Play again(Resume)-Next-Close)

VLC
3 buttons
"Play" button (by tapping, turns to "Pause" button, tap again, resumes)
"Next" button
"Stop" button
with 5 behaviors(Play-Pause-Play again(Resume)-Next-Close)

MaterialPlayer
1 button (appears when user taps-slides down on app on status bar)
"Pause" button (by tapping, closes)
with 1 behavior (Close)

----logfiles while tapping on notification bar control.

Again, it's matter of preference, and depends on user taste.
Though, position changer on the notification bar could be useful.
Something like these, maybe?

from voice.

Gave the notification a high priority, so it should be on top and expanded if there are no other applications who implement a max priority (like emergency calls).
