You've suggested two new interesting ideas. I'd like to hear if others think they
would be useful.
1. A way to step the plot view through time. Rather than dragging a slider to a new date,
in a new date, have an "advance" button (say) that would move the date ahead by
2. A way to advance the selected parcel in the order of the Table View.
Regarding your third comment about sorting the table view and how it relates to the text
I don't understand the problem. Can you elaborate?

Subject: Re: [DMU] Proposed "As of Date" feature
I'm not sure exactly what the slider is you referred to in your earlier
email so perhaps you're already thinking along these lines, but.....would
there be some way, possibly as an expansion of the proposed "as of date"
filter, to allow us to specify a start date and an incremental time span (1
year, 5 years, 10 years, etc.) and then click on an arrow that would apply
the filter to the next increment in the date series? And as an option could
sold dates apply or not apply?
I'm thinking how useful it would be in the plot view to move through a sort
of slide show of tracts (possibly filtered by other criteria as well). It
would help to more easily visualize how a tract (or tracts) changed shape
and ownership over a sequence of years.
I was thinking along these lines:
1. pick an initial "as of year" - say 1800 - all parcels owned as of that
date show (assuming they meet other filter criteria if applied)
2. use forward arrow to move to next "date parameter" - say if I had
designated a 10 year sequence the filter would then show all parcels owned
as of 1810. If a tract was sold in 1807 and I'd entered the sold date it:
a. would not show up if I selected to include "sold dates" as an
b. it would still show up if I'd opted to deselect "sold dates".
This would allow deeds in a given area to stack on top of each other
chronologically - allowing me to visualize how boundaries changed with later
surveys, parcels were subdivided, etc.
Alternately (or in addition), would it be possible to sort the table view by
date, then switch to the plot view and move to the next deed in the sorted
sequence without having to go back to the table view? With the addition of
appropriate text filters, this would allow the user to highlight, in a
chronological sequence, deeds impacting the same tract or cluster of tracts.
I know that I can sort the table view by date but I have to select the deed,
tab to the plot view, tab back to the table view, select the next deed, tab
back to the plot view, etc. (unless I've missed some way to do that now)
I also wish a temporary sort change would remain in place when I switch from
table to text view. I know I can select (Tools>Sort>Permanent) and then the
sort "sticks". But that seems to reassign the item numbers and I don't
to permanently change them which I assume would happen if I then hit Save to
save other changes.
Thanks. I know I don't want much :).
BTW, thank you SO much for having added the "undo" option.
