If I try to upload a file to a website (like uploading an image to an image board for example), it would be very nice to have some extra actions available when I right click a file from the file upload dialog. As it is currently, we only have 2 actions to choose from when right clicking in that dialog.
1. Show Hidden Files
2. Show Size Column

I spend a fair amount of time trying to introduce people to KDE and one of the few common complaints I hear from people that does not seem to have a solution is the inability to open or rename files from the file upload dialog. Any chance of having these actions added to the right click context menu?

Reproducible: Always

Steps to Reproduce:
1. visit a website with a button prompting a file upload dialog
2. right click on a file within the file upload dialog
3. As you can see there are only the 2 actions I mentioned above and there is no way to open a file or rename it from there (opening dolphin and navigating to the same location to open/rename is not an ideal solution in my opinion)
Actual Results:  
Only "Show Hidden Files" and "Show Size Column" appear in the right click menu

Expected Results:  
It should show other available actions as well. Here is a list of the actions I think should be included

right-click->
1. Rename
2. Move to Trash
3. Delete
4. Open
5. Open With
6. Properties
