• Tray tool tip is electron, not wnr. (After the tray icon is added manually.)
• Left clicking the tray icon only has the same effect as a right-click. (After the tray icon is added manually.)
• Focus is given to the menu icon (at the top-left corner of the main window) after making the main window shown up by the 'Show / Hide' button from the tray menu. (After the tray icon is added manually.)
• Virtual desktops are not blocked by full-screen focus mode.

Thanks!
I assume the tray stuff be practical to be fixed, however, the last bug may need to make a complete new solution for it in the worst occasion (hopefully not, or a specified warning giver function might be a must...)
Also, if you are free, you may check about whether all the settings items really do their jobs fully on Linux, thank you dude.
Moreover, other things like the electron-build bridge (/res/builder/ to set) might get broken.

The right-click and double-click events of the class Tray are only available on macOS and Windows. This may require a change by Electron.

Yeah, you're right. Currently I can bear with the workaround of disable the former left-click behaviour of show/hide on Linux. Or if you feel like it, you can issue it to Electron.
And, is the transparent icon fixable or that you can go with it?

Anyway, I think I'm gotta release the new version. In case you have some new ideas, I can perform a hotfix to the release, which is to say, to replace the appimage of the release manually.

This transparent icon issue does not affect normal use, only looks a bit weird though. I'll open another issue with more details later.
