3D model select dialog does not use standard file dialog layout and location selection

[[e-mail]]

Steps to reproduce:

 * Open project in kicad
 * Open pcbnew
 * Press 'e' on a footprint
 * Go to '3D settings'
 * Click Folder button to add a new 3D model

In the dialog a system-wide 3D model directory is open in the left pane, but project directory is selected in 'Paths' dropdown -- see attached screenshot.

I would like the left file selector pane to display the project directory as selected in dropdown by default as usually I have my custom 3D models in my project directory. Now I have to select any other directory in paths dropdown, then select my project directory again for the file selector pane to update.

I cannot agree more that this selection dialog needs to be fixed.

[Wayne Stambaugh (stambaughw)]

@Seth, I agree that the file selector part of this dialog needs some work but the user is only requesting that the default path is the current project path. In principal I agree with this but there is an equally valid argument that the default path should be where the 3D models are located. I personally prefer the project path but that may not be the consensus.

[Seth Hillbrand (sethh)]

@Wayne- We currently have shortcuts for the project directory (and other standard paths) in the dropdown menu at the bottom. Because the project path is selected in the dropdown but not in the tree, the user needs to select a different item and then back to the project path. We could simply make the dropdown match the tree (maybe even for 5.1.1?).

However, I've had fixing this dialog on my list for a while, so rather than partially patch it up, I'd like to fix completely during 6.

All I am concerned with is discrepancy.

It would benefit me personally if it was both tree and dropdown on the project directory, but I also would be fine if both dropdown and tree would point to the system 3d model folder.

From my experience, all the existing footprints already have 3d models assigned to them, so as I am creating a new footprint I also download or create a new 3d model for it - usually in the project directory. Thus in my opinion it is better to show project directory by default, but I will not force this opinion on developers as I know everyone has their own workflow.
