Management of the LOG file through the web ui

One immediate thought from a first time user is that the log file should also be made available through the web ui interface.

It would then be useful to be able to sort and filter on date and message type (e.g. error, warning, info..).

Config of the log file behavior should then also belong here. Probably other more experienced users have useful input to this also.

Agreed.
I believe there is a request for this on bug.flexraid.com (bug and feature tracking system).
If not, try to add one there.
