PrintPreview1 with zoom buttons and scaling factor widget circled

In the attached "PrintPreview1", I claim that the "scaling factor" slider widget (circle (1)) is not visually clear as to it's purpose.

I originally clicked on the buttons expecting the behavior one gets when clicking the +/- buttons in circle (2).  When I did not get the desired visual appeal, I thought again that maybe I was messing with the margins.  It finally dawned on me what it was doing (see "PrintPreview2", but it took me more than a few seconds to kick myself from my preconceived notions.

I submit that this could/should be made more visually explicit before 3.5.  Unfortunately, I'm not a UI guy or I'd offer a suggestion.

This may apply to other LO components as well, but I was using Calc when I noted it.

This screenshots were made with master.  Last pulled commit:

Not a particular Master problem, I also see it with LibO 3.3.3 Portable. Behavior is inherited from OOo, I also see it with OOo 3.1.1
No idea for what that is needed
- we have a zoom slider in the status bar
- no help available (see Bug 42081 - LOCALHELP for CALC 
  Page Preview Bar incomplete)

I can't find out any purpose for what that slider might be useful.

@David:
Please add findings to Help (also see "Bug 42081 - LOCALHELP for CALC Page Preview Bar incomplete").

Confirmed it's still the same in Calc. Giving to the design team.

Zoom (2) works similar to ctrl+wheel or the statusbar slider - it zooms into the document. The slider (1) scales the content, meaning you get more columns on one page with "-" or enlarge the font with "+".

The interaction has a clear feedback but the UI is missing a label "Scale" before the slider. The usability would also benefit from showing the actual scaling factor and when +/- steps become more discrete. 

Sounds like an easyhack.
Comment 8 Heiko Tietze 2018-01-03 15:13:45 UTC
The scale slider is handled in sc/source/ui/cctrl/tbzoomsliderctrl.cxx with a constant nSliderXOffset to both left and right that should be changed into an asymmetric offset to allow the output of 'Scale' before the slider, and perhaps also the current value right of it.

As I understand,I need to create label before slider and its actual value on right side in previewbar .

Exactly, there should be a translatable caption with the slider. I would also like to have the actual value on the other side. And when you touch the code and find an option to increase the steps when the user clicks on + or - that would be great. Sounds like we ideally go with a standard control, if there is one.

But having just a caption on the left side is fine at the moment.
