Just downloaded everdo-1.3.5.pacman and received the following:
warning: cannot resolve "libappindicator-sharp", a dependency of "everdo"
Which results in:
error: failed to prepare transaction (could not satisfy dependencies)
FWIW the comments on the AUR package indicate that libappindicator-sharp is not a needed dependency. It was removed there and, based on the lack of comments afterwards, it would seem without issue.
Attempted on 5.6.11-arch1-1 with Xfce 4.14
