I tested various configurations (version 2.5.4 and 2.7.0, 32-Bit and 64-Bit, with setup and portable).
-Scanning of font folders (notably, Wine seems to properly present both /usr/share/fonts and /home/
-Searching for fonts
-Adding and deleting custom font folders
-'Copy to Folder' action
-Viewing font properties/charmap windows
-Export as image
-Changing font preview properties (bold/italic/etc)
What does not
-'Uninstall Font' appears to do nothing.
What was not tested
-Duplicate font search
Performance seems excellent - I have 2.4k fonts and the scan at program startup is only a few seconds, and there's no lag skimming through the preview list.
