improve internal links, make it more obvious which file was shared

[schiessle]

If you open a internal link to a file you get navigated to the folder and the file gets highlighted with a light gray background. But this is really hard to discover.

My suggestion, to make it more obvious which file was linked to:

• open the sidebar for the corresponding file
• have a visual effect on the line. Similar to the the top-left menu if a new app was enabled.

If the file is viewable, like if it is a txt, pdf, image, video or other where a viewer is activated for, it should even get opened directly. Is that possible?

I think we are running out of time for this item. I would say we need to move this to 13
