QtDragon was never intended to be used with an ATC but I could certainly look into it. It would only affect the tool table when using a tool setter, not a touchplate.
As for the dialog, add the following to your stylesheet.

QDialog {
    background-color: gray;
}

QDialog QPushButton {
    width: 100px;
    height: 40px;
}

Adjust the color or any other parameters you like to suit whatever stylesheet you're using.

In 2.8 the macros for probing are in nc_files/probe/basicprobe/macros

[RS274NGC]
SUBROUTINE_PATH = ../../../../nc_files/probe/basic_probe/macros

looking at the macro for touch_plate.ngc:

o<touch_plate> sub

#<max_probe> = #<_ini[TOOLSENSOR]maxprobe>
#<search_vel> = #<_ini[TOOLSENSOR]search_vel>
#<probe_vel> = #<_ini[TOOLSENSOR]probe_vel>
#<touch_height> = #<_ini[TOOLSENSOR]touch>

(print, max_probe is #<max_probe>)
(print, search vel is #<search_vel>)
(print, probe vel is #<probe_vel>)
(print, touch height is #<touch_height>)

G21 (use metric units)
G49 (cancel tool offset)
G10 L20 P0 Z0 (clear current offsets)
G91 (switch to incremental mode)

It sets metric for it's process.
I'm sure there is away to record the current units before and restore them after.

I did some digging and found that QTDragon doesn't use the macros for the probing that happens on the Offsets and Tool screens. It is done in the Python code in qtdragon_handler.py file. I'm going to attempt to make a change so that any values that are shown, entered on the screen or in the .ini file are treated at units in the specified by LINEAR_UNITS in the .ini file. Having some values in MM and others in Inches is confusing. If successful I'll have to learn how to contribute changes.

The macros are used for the probing done on the Probe screen. This is a great learning exercise.
