Is it possible that you can develop a function so that JDownloader can analyse the dimensions (ex. 1920x1080) of a video source, images, etc. before downloading them (so alreadu show those dimensions in the LinkGrabber)?

It would be great to know the dimensions of a source file in order to filter on minimum dimensions, have a column in the Downloads tab to sort, and a view in the LinkGrabber tab.

Such a feature will only be possible for sites/services that provide those information without actual download. For this feature to work you would have to actual download/peek into the final download = wasting download slot/wait time/captcha/IP block, just to *maybe* (because requires range support, only often for premium only user) be able to determine those information.
Some plugins (eg YT, vimeo) can already place those infos in filename but for normale hoster sites this won't be possible/added
