As I use a Surface 3 Pro as well I was wondering what you were saying, then when I looked at your screenie's I understood, you really do scale up, I run default noscaling.
However for me I use the panels as "quick glance" only, when it comes time for skill checks, weapons, spells etc. I switch over to that tab, which may be why reading the panels is not such an issue, however I do like the view with it scaling somewhat. Going to play with this a little.
I started with no scaling (btw, you can right-click properties and turn it on/off for individual programs), I was like, wow, I can see EVERYTHING. Problem was, I need to use the pen now, everything was too small to click. and really, just to small in general. It's much nicer when a program scales itself for HDPI (see latest Photoshop as example).
Personally, I like to keep the In-Play tab up, it's where most of the action is. Occasionally flip to spell tab to cast or Specials tab to get details on something, and I would like to just view somewhere in a summary or such to know my attack/damage numbers easily.
What I get instead is.
Round 1
<InPlay>check power attack
<weapons tab>attack
Round 2
<InPlay>check smite
<conditions>check flanking
<weapons tab>attack
<InPlay> record damage
Round 3
<Weapons tab> hmm, that's not right
<InPlay>uncheck smite
<Weapons tab> oops, still not right
<conditions>uncheck flanking
<weapons tab> attack
<specials tab or paladin tab>check mercy/LoH dice, roll
<InPlay>heal damage
If we could reduce tab flipping some, I'd be a happy camper. A conditions summary tab WITH checkable boxes would be lovely. I constantly need to go to that tab for flanking, charging, defense, etc. Combined with text reflow for weapons tab, I could pretty much sit on the In-Play tab most of the time...
