By the way, can anyone here send me a mantra for osgeo registration?

You're welcome! I definitely want to contribute to the project and make
it better. Only replying to the spots where you had questions.

I'm not an expert on tooltips (maybe I can find some academic papers),
but my sense is that there is a fundamental conflict that is
irreconcilable: the more complicated an application, the more having
a faster tooltip is important for letting new user learn it. But the
more experienced you are in an application, the more annoying tooltips
are, and the slower you want them to be. So I suspect that getting
the tooltips fast enough to be good for new users is going to make
them atoo annoying for experienced users.

But when I get some time to sit down with the QGIS 3 / Qt 5 build (Qt
4 didn't support adjustable tooltips), I'll try to evaluate this. 

I do think worrying about making the Options dialog big and scary is
kind of unfair. QGIS already has a *lot* of options, one more isn't
going to break the bank. And if this was a real concern, you could
throw it under Advanced.

Although that's a little counterproductive since the entire point of
the adjustment would be to cater to new users. Although I suppose
the default could be new-user-speed and only advanced users could
slwo it down.

I think Nathan misunderstood me, since he referenced widget padding.
I didn't mean the visual appearance (scale) of the arrow widgets,
I meant the default quantum of adjustment.

Specifically if I have text in as "10 point" and I switch the
adjustment to map units, "10 map unit" text is unreadably small.
In this particular test, which is the alaska.shp from the sample
dataset, it shows at scale 1:17,433,906 and magnification 100%.
To get the text readable, it has to be 10,000 map units. 

I would have to click the up arrow tens of thousands of time to get to
a point where it is visible. I'm not sure what the right solution here
is....maybe the arrows for map units should go at logarithmic scales?

Also, is something wrong with this shapefile that it shows up at
such a huge scale factor? It's much larger (17 million) than the biggest
scale factor in the scale factor dropdown (1 million).

It probably is OSX-specific.
Trivial to reproduce, and seems to happen in ~all cases, but here's one:
New Project; Add Vector Layer: airports.shp; Layer styling: Labelling;
Show labels for this layer; Label with NAME.

The font shown is Helvatica, but the face dropdown is empty.  Switch
to Helvetica Neue, the dropdown is populated.  Switch back to
Helvetica, it's populated (and the defauilt is Light Oblique).

I agree it's common for Paste-In-Place. But I also suspect more QGIS
users use it for Add Vector Layer. Also this is not a huge deal -- I think
it is an example of novelty and that novelty breeds confusion, but I don't
know that this particular case is actually all that confusing. *shrug*

Well, then that's a great reason to make them all consistent and use
Opacity! (unless there's strong precedent for Transparency in mapping
apps).

Eh? Layer Styling: Symbology gives me No Symbols, Single Symbol,
Categorized, Graduated, Rule-Based, Point displacement, and Heatmap. Are
you saying it should be in htere next to Categorized nand Graduated? It's not.

Understood.

I'm not really a GUI developer, but I can make some effort at this.
