Install Updates - Yad version

Vera:
I did the same as DenW yesterday (I used the first block of code but with my window slider setting moved back to the left to check for window centering). Windows were now centered during the update process! Yay!

However, I still got the moving blue bar. So that part sounds different to what DenW was seeing. I'm not sure why it was different for each of us.

I did this before Jerry posted the new block of code, so I'm not sure if the timing had an effect (did we maybe get different versions of the old code, DenW?) That part is confusing to me but I definitely got the blue bar. I remember it because I was contemplating whether the moving of the blue bar seemed slower or faster than it was before (ultimately neither one, as the rate seemed to vary during the process).

My next step is to try Jerry's second block of code. I will post again after I try it.

DenW:
Hi Vera/Jerry: Thanks Vera for your kind words and good to know moving slider solved problems for you.

Jerry, I just copied the code from your original post (I think - because I did not see your latest post!) and installed in my updates-gui. To be sure that it would be your code was doing the centering I moved my Window Placement slider to far left (small) and then ran Install Updates. Worked perfectly with all windows centered but I did notice no blue bar except during download (thats why I wonder if I got your latest version anyway).
I know I commented in a previous post elsewhere about getting rid of the blue bar but I think I was premature because the updates at that time were small. During a kernel update yesterday, and even with todays updates, I did notice significant pauses in the text changes during all phases of the update. Even though it clearly states "this may take some time" I found I missed the reassurance of the moving blue bar as the text was sometimes sitting there for 20-30 seconds or more, which can seem like an eternity! Does anyone else have a preference?

Jerry:
What if there were no progress bars, just simple text output during:

- Updating packages
- Installing packages

and only a progress bar during Downloading of packages?

Jerry:
Code updated. Please copy new code from original post.

Change - all windows will now center screen regardless.

Cheers.
