Sometimes the window gets unresponsive while handling a lot of files. That's why I suggested priority similarly to how archive managers handle things. I'm not sure if it's possible.-neverlight
Unfortunately, that unresponsiveness has nothing to do with the process priority. It has to do with the fact that the UI is waiting for the commandline sigcheck.exe to finish. There are a few different methods I can use for this so it might be something I can alleviate.
Also, it would be very interesting to see a cache system that might speed up the process since some files might have been (already) processed.-neverlight
Doubtful that I'd add this.
Perhaps there should be another action in "View" tab that gives end-users the ability to show only unique files (not duplicates).-neverlight
I can add an option like "Skip duplicates in list" or something like that. If this is enabled, files that already exist in the list will be skipped. I'd think the full path would have to match exactly for this to be useful, though.
Another issue that I've observed is that it does not handle special characters well. Probably a display issue.-neverlight
The app does seem to handle Unicode paths and Unicode filenames without issue so I'll assume you're talking about the actual displayed data. If so, can you provide me an example of what you're seeing?
And another suggestion would be to rename "Trusted list" to "Trusted Vendors" as this might avoid possible confusion & make the box re-sizable.-neverlight
Can do.
Also, the clean action will not do anything if files are being processed. I'm guessing this option could be grayed out or/and inform the user that it is not possible, maybe.-neverlight
Can do.
Under "Help" tab > "Contents", users would expect a help file and not a pop-up that describes SigcheckGUI since there is an "About" button. Superseded.-neverlight
Ah, help files. The bane of developers everywhere.

I'm terrible at providing them.

That said, I do try to write my applications such that, hopefully, a help file shouldn't be needed for the most part.
Another suggestion that might be useful regarding quick access would be to add another action in the right-click menu named, for example, "Open File Location".-neverlight
Can do.
Maybe, the "Info Box" action from right-click menu should be grayed out for multiple files.-neverlight
Good point.
SigcheckGUI or SigCheckGUI -- Is it intended?-neverlight
I've seen both. However, the
official site for the sigcheck.exe program that does the grunt work has it spelled Sigcheck so that's what I went with.
