The report must also include at least one of the following:

   See above

2. A screenshot of the application window (if it is a graphical issue).

Additional context
You are free to add any other context about the problem you deem helpful here.

IMPORTANT - Getting the full log

Normally, the application log is shown upon pressing the "LOGS" button in the bottom left corner of the window.
Despite it having some value already, there is a more detailed version saved each time qFlipper is run.
In order to access it, follow these steps:

1. Click the "LOGS" button to open the log window.
2. Right click on the log window.
3. In the context menu, select "Browse all logs...".
4. A folder containing several log files should open.
5. Find the most recent file, this is it!

Warning! The log will contain your Flipper's unique name. If you wish not to disclose it, search/replace
all its occurrences before attaching the file.
