I like the plugin and it's simple interface with several options.Especially, options for custom dashboard widgets and logout redirection are great
I don't know if you accept feature requests . But would like to suggest a few. For multisite installation , this type of plugins are very much needed to keep Admin panel simple
1) For multisite installations, Unified plugin settings to enable and disable options for all the sub sites
Exclude site wide options for certain blogs mentioned in a custom field
2) Option to add timer for 'Maintenance mode '
Thank you !
