image size and retina problems

I am a new user of FRV, I found no where to display the image size (in pixel) of an image: the status bar, the EXIF panel and histograms. The file size (in bytes) can be found, but not the image size.
Another problem is related to retina display: in 100% mode (via Cmd+1), the image looks blurred (or maybe because it was zoomed), not as sharp as in Photoshop. I guess that in Photoshop, the pixel size is equal to the physical pixel size, but in FRV, the pixel size is the scaled pixel size. I set "Default for display" in system Preference, the scale factor is ~2x. Please take a look at the screenshot, the left one is in FRV and the right one is in Photoshop.
Thanks.

To add image size and zoom

To add image size and zoom ratio on bottom bar go to Menu - File - Customize bottom bar and add 'Current image size' and 'Zoom ratio and zoom buttons' to 'always' or 'if fits' column. These controls/displays are turned off by default because not all users use display wide enough to fit all possible data.

On Mac you may also uncheck Menu - FastRawViewer - Preferences - Zoom - 'use logical pixels for zoom calculation; This settings affects only zoom value displayed.

FastRawViewer uses fastest possible demosaic method, this method is not as sharp as best possible (but slow) demosaics used in full-scale raw converters (e.g. Adobe Camera Raw/Lightroom). Also, all raw converters apply some sharpening on image even if 'sharpening' slider set at zero. In FRV you may try to use screen sharpening on (Menu - View - Screen sharpening, or 'S' key, or 'USM' button on bottom) to increase visual sharpness of image.
