This seemed like a great app, thank you for making it available. It was working great, now it keeps scrolling to the top of the file while I'm reading in the middle. It seems to tail properly if I'm looking at the bottom. It was doing this in 1.40.4 installed via WinGet, and also in 1.40.5 extracted from a zip.

Update: If I close the app, rename my %AppData%\settings.json and let it create a new one, the same issue is happening

Possibly related - when I try to export my highlight rules, I get this:

Filter string you provided is not valid. The filter string must contain a description of the filter, followed by the vertical bar (|) and the filter pattern. The strings for different filtering options must also be separated by the vertical bar. Example: "Text files (.txt)|.txt|All files (.)|." (Parameter 'value')\n\n
