5290	OMEdit should look the same on high-resolution, high-dpi screens	Francesco Casella	Adeel Asghar	"The recent trend on laptops is to use high resolution (full HD or even 4K) screens on 13- or 14-inch screens. Modern OSs such as Windows 10 support this feature, allowing to show text, buttons and icons with higher resolution, rather then making them look too small. However, applications need to be fine-tuned to work properly in this context. Apparently, OMEdit still has some issues from this point of view.

I just moved from a laptop with a 13-inch screen at 1366 x 768 to a new one with full-hd resolution 1920 x 1080 on a screen of the same size. 

In the first attachment, I report an image obtained with the settings of the text width at 100%. Everything is super-small, but that's how also other applications look like, so I guess it's ok, except for the big {{{'+'}}} node icons in the package browser, that show up after a while and look quite odd. When OMC is just started, small arrow heads are shown, which look much nicer, I have no idea why these big things show up after a while.

Since my eyesight is not good as it used to be, I often work at 150% size, which is the recommended setting. OMEdit looks as shown in the second attachment. There are many elements that have scaled up nicely, such as the menu titles, the font of the library browser, the icon and text in the Welcom|Modelling|Plotting|Debugging tabs, and the font in the log window. 

Other instead have remained at the same size as the 100% case: the window title bar and icon, the icons of the button bar below the menu bar, the font of the documentation browser. 

Others still have increased their size too much: the lines used to draw the icons and the connection lines in the diagram view look much thicker than at 100% resolution, when the diagrams are scaled to occupy the same real estate on the screen.

I would recommend the following actions:
- make sure the big {{{+}}} icons do not show up at all in the library browser
- set the font size at 200% (so the effect is even stronger) and make sure that
  - all graphical and textual elements in the OMEdit windows double their size when doing so
  - the diagram view looks the same when zoomed up to the same physical size on the screen

This will be particularly important as screens with really high resolution (such as 4K on a 13"" screen) become the norm in a few more years. Applications that don't scale nicely will be unusable, or at least look very old-fashioned.

I would recommend this issue to be fixed for 2.0.0, possibly earlier."	defect	closed	blocker	1.17.0	OMEdit		fixed		Andrea Bartolini
