Yes, it’s good, but a couple of teething issues, wait till later today or tomorrow AM before trying..

Tried 1.4.4. UI feels slower than Mate but everything seems to be working. RTC now works! Didn't in 1.4.3

Right, KDE still needs more tweaking to make the experience smoother.

Jasem - you are going to stay with KDE from now on, right? I wonder why you went away from Mate..
(I just recently learned what Pluma was. Now it's Dolphin)

KDE is the natural environment for KStars, since KStars is a KDE application and uses its library and services...etc. With RPi4, KDE is usable now for the most part.

I am getting a blank screen from the latest iOS app when trying to connect to the StellarMate hotspot with the pi4 with 1.4.3 and 1.4.4

Please delete and re-install the app again. I think yesterday, there was an update that caused this and it will removed afterwards.

I tried deleting and redownloading today, but quickly got the blank screen again

OMG. It was such a stupid mistake of mine...
I was trying different options to feed RPI4.
-- 2.1A charging port of a USB hub (12V input)
-- two charging ports of the USB hub in parallel = 4.2A
-- 6A 12-5V converter
First two options were extremely unstable (RPI would just shut down after 5min-1hr).
The third option was more stable but also RPI would occasionally shut down.
It turned out that I was feeding the whole thing (RPI, hub, cameras and mount) with a 1A 12V wall wart instead of 5A power brick!
(I have four 12V battery chargers and one 12V power brick plugged to a single power strip - all have the same kind of output cable).
Once I figured this out.. All three options worked. I currently use the second.
SM 1.4.3 -all works (except for RTC) and stable
SM 1.4.4 -all works (RTC too!) and stable

I am surprised it ran anything at all from 1A.... ?

Ah good ol' layer 8 issues...

but it did! the wart was very hot though (that's how I discovered my mistake)
i guess, the system drew much more than 1A from that wart.
