In the "Preview" window, there is a button (pencil icon) that allows you to edit your image with an image editor app.
The first time you EVER select this button, you get a (limited?) choice of image editing apps on your computer to use as the editor.
After you chose one, you can NEVER change it to another app.
Feature Request:
1.) Could you allow a RIGHT CLICK on the button to let us select a different app than the one that has already been chosen.
2.) Also, not all image editing programs I have on my pc showed up in my pop-up list to chose from.
Could you also allow the user to SEARCH for an app that isn't shown in your "Edit With" app selection window,
kind of like how Windows does with their "Pick an app" pop-up selection window ("c:\WINDOWS\SYSTEM32\OpenWith.exe") when you try to open a file with an extension that isn't tied to a default program. Their selection window shows you a list of suggested apps, but also lets you search for another app if the one you want isn't shown.
========================================================
For those wishing to change your image editing app to another app (if you've already selected one and until this is fixed), you can do the following:
You will need to delete the following two lines from your NAPS2 "config.xml" file (and save the file).
Then just chose the Edit With button again and you'll get your image editing app choices again.
My config file is located at: C:\Users(my user name)\AppData\Roaming\NAPS2\config.xml
NOTE: The image editing program you selected will be shown on these two lines. I selected Paint.
config.xml
<editwithapppath>C:\Windows\system32\mspaint.exe</editwithapppath>
<editwithappname>Paint</editwithappname>
In the main NAPS2 window, you can click the Image menu and will have 2 options ("Edit with MyApp", "Edit With...").
