There is now a "Display Cover Art" menu option (under the View menu). If you are playing a blorb file which contains a cover art image, this will pop it up.
The app is now responsive to the OS dark/light theme. App windows like the IF Card and Preferences windows will be displayed in dark or light mode as appropriate. Game windows will still display in your chosen color theme, but there are new system themes "Light/Dark" and "Sepia/Slate" which adjust automatically based on the OS setting. The default theme is Light/Dark, so new Lectrote users will see games use their OS theme.
Updated to Electron 8.4.1.
Note: Electron has deprecated 32-bit Linux support. The linux-ia32 package is still included, but it may not work. If it does work, this may be the last Lectrote release that includes it.
