Hi,
As many of you may have already noticed, any change to estates or tax rates drains one hour of the Lord's timepool.
What I propose is to add a "commit" button to the page, in order to let a Lord play freely with the various percentages for his estates without losing any hour: otherwise just to see how efficiency and income vary according to the percentages can easily take more than one turn, which is frankly annoying and a bit unreasonable.
Whether this proposed commit button would allow a Lord to make many changes at the same time spending a single hour or not can be further discussed as an addition to the feature request. Personally I would see no reason not to allow it: even only to accommodate a single more knight in a region already fully covered by estates one needs to perform many tiny changes, requiring a lot of hours unnecessarily.
thanks and cheers
