Hi,
might there be a possibility to add new locations to the left hand (Look In) pane on the Open File Dialogue?
Selection of <User> takes me to the windows standard <User> drive:\folder (normally ‘C:’).
For <reasons> I have my application-data folders (not ‘C:\program files’) at a location that is also available to my parallel Linux installation (consecutive, NOT concurrent access!) In view of the multitude of ‘clicks’ required to navigate through ‘My Computer’, it would be more comfortable to be able to add additional / alternative locations.
I wrote this as a suggestion because I have not found a way to fudge this functionality, or trick the application into allowing this. If there are any gurus that may have magical (Registry?) hacks, I would like to hear of these.
I’m pretty sure Seamly gets the file dialog from the system. At least in my XFCE Devuan Linux install that panel has all the folders I have available in my thunar side panel. So it does have the Seamly folder I have on a shared device.

Ok… if I understand correctly… you want to see more shotcuts in the left sidebar:
That said… currently the file dialogs use the non native dialogs.. for we which could popluate the sidebar with more shortscuts OR switch to using the native dialogs.
The issue has been that until rencently Seamly did operate in Dark mode… and if your system is set to use Darkmode the dialogs will open like this on the Seamly screen:
instead of this:
We basically have two options… switch to the Native dialogs - which may still present the issue of a dark dialog on a light Seamly OR add more shortcuts to the non native dialog. Question is what shortcuts to add? They can be different on every machine. 
Personally I’d prefer just using the native dialogs. Less work to implement, and in many cases any one using Dark mode for the system can now use Dark mode in Seamly (with a few caveats). Also it’s not the end of the world to see a Dark dialog on a light Seamly screen.
All in favor of Native Dialogs…?
All in favor of keeping the Non Native Dialogs…?
Update:
There’s 3rd Option… I could add a Preference and the user can choose.
All in favor of a Preference to use Non Native or Native dialog?
The dark one is the native dialog? But it would be bright on the light scheme?
And the second one is non native dialog? This is what we have now, no?
I am missing only Quick access there, but yes, this would be just a personal way of using data
Yes… or what it would look like in Seamly - the screen cap is from Librecad.
Not if the system is set to using Dark mode… like mine is. And that’s been the issue. Until recently Seamly was basiclly a light mode app.
Yes
The Native dialog uses the Quick Access, the Non Native does not. It’s why I’m in favor of just using the native dialog… as the dialog will then mirror what you see in the File Explorer or Finder… and what ever Linux uses.
I prefer the concept of native dialogues. It’s basic behaviour and, if I understand correctly, easier to implement.
Non-native dialogues would only make sense if they could be personalised, but that sounds complex to me. I don’t think there’s any need to complicate things at this stage of the programme and invest more work in that.
Exactly. Again the only reason for the non native was a dark native dialog on a light Seamly screen.
BTW… Correction… the non native dialog only apply to Windows. I forgot @csett86 set the Mac and Linux versions to use the Native dialog… In my memory I thought it was only for the color dialog, but it was for file dialogs as well:
#ifdef Q_OS_WIN
const QFileDialog::Options FILEDIALOG_OPTIONS = QFileDialog::DontUseNativeDialog;
const QColorDialog::ColorDialogOptions COLORDIALOG_OPTIONS = QColorDialog::DontUseNativeDialog;
#else
const QFileDialog::Options FILEDIALOG_OPTIONS = QFileDialog::Options();
const QColorDialog::ColorDialogOptions COLORDIALOG_OPTIONS = QColorDialog::ColorDialogOptions();
#endif
i just built Seamly using the Native file dialogs… this is the point I was making when using native dialogs with the OS in Dark mode and Seamly in Light mode:
The native dalog palette can be hacked in Windows, but not on the Mac where the file dialogs are sandboxed. I don’t think it’s worth the effort. I think the best solution is give the user the option of which dialog to use in the prefs.
Ok… I went and just added a pref to use native dialogs or not.

The pref applies to both file and color dialogs. Note: Widows uses the same color dialog for native and non-native while Mac and LInux have their own native color dialog. The default is ‘Use native dialogs’.
@DavidDeb… I hope this satifies your request. 
Hm, my windows (10) ‘Colors’ setting was already ‘Dark’, I then set the default app mode to ‘Dark’, the net result is as below …
However, as in my previous moaning about the file open dialogue, I can live with this.
Since all of my efforts are directed towards a transition to Linux - which cannot be 100% because some of my software smiths (e.g.: Wilcom ‘Hatch’) are not going to produce Linux versions of their applications - could I get the Linux version (Linux Mint 22.3 “Zena”) to show alternatives to the default location(s)
