great idea, endorsed!

There are a couple of reasons.  First, and this applies more to some types of printers with more of a "hot spot" than others, a mask that adjusts for exposure across the entire build plate could increase exposure time pretty considerably.  In my case an additional 30%.  However, if a particular print run only needs 50% of the plate then a custom mask will result in a pretty significant reduction in that 30%.  Second, as mentioned above, and I am still working on this case, a custom mask could be created (from a mask that already adjusts for the UV)  to divide the build plate into exposure areas.  Each area would be a different exposure, as adjusted using the mask.  If the same calibration model is placed into each exposure area you have another way of fine tuning a profile.

True...and would probably meet most use cases.  It does not help with truly customizing the shape of the print area on the build plate as it precludes an adjustment where you want to use the plate from top to bottom but not all the way to the edges...or the opposite case where you have a long but narrow part so you are only concerned with the middle of the plate from long end to long end.  And it does not help my second case.  But it would be a start and an easy implementation I presume.

Related question.  If the mask file is changed...does the application need to be restarted or would the new mask file be read the next time a plate is added or recreated?

On recreate the mask get reloaded.

Love, love, love that the CSV import feature is in the beta!  Unfortunately it does not seem to work for me?  I could be doing something wrong though.  I paste in my matrix and then press the update mask button.  While it does remove any previous mask from the preview panes it does not change the values in the entry matrix nor in the grid preview?

Works like a charm.  I stopped and restarted the browser but that didnt work so I deleted history and that did.  The Mask Preview and the Final Mask both updated and the entry values filled themselves in.  The Grid Preview, however, needs to have an update forced as it did not update until I changed a cell in the entry form.  Thanks for doing this!  I had started to write a Python script to save me the trouble of entering 50 data points for each of a number of masks that I need.

The other thing that would be really nice is if the SW remembered the dimensions used for the mask.  (5x10 or 10x5).  Is this a setting somewhere?

Thanks again, Will

You are right...no need to specify the size if it is detected for you!  Works like a charm.
Thanks for this add.
