Make BlackNotepad Open a Double-Clicked File Without Doing an Additional File > Open
Is your feature request related to a problem? Please describe. I installed BlackNotepad v.1.0.9.0 through the Microsoft Store. I managed to set BlackNotepad to open .txt files by default using my Windows 10's Settings.
When I double-click an existing text file within File Explorer, BlackNotepad launches, but as a blank file:
The same behavior occurs when I right-click a file and choose "Open".
In order to access the content of the document, I must click File > Open each time I am opening a document this way.
Describe the solution you'd like
It would be awesome if double-clicking a .txt file (and right-click > Open) would result in BlackNotepad both launching and opening the document that was double-clicked, without the need to click File > Open every time. For example, after double-clicking an existing text file called Foo.txt, BlackNotepad should open as follows:

Describe alternatives you've considered Since the desired behavior that was mentioned in the Describe the solution you'd like section is how Windows' Notepad behaves (and is, perhaps, the most intuitive behavior,) I couldn't come up with alternative solutions.
Additional context I searched the internet for alternative solutions, such as running a command each time a file is double-clicked, but this solution applies only to application files (e.g., .exe,) and one needs to repeat those changes per every instance of a file they wish to open this way. I couldn't find other applicable solutions. In addition, I tried my best to look through the existing issues, but none is closely associated with the particularities of this feature request, which is the reason this issue was created. I apologize if I missed anything. Thank you very much for your consideration!
I have the exact same problem, I don't found another alternative
