Enhancement - easy to use figure template
More of a suggestion than an issue:
Much time is spent setting up figures: import head data, make contours, import well locations, observations, simulated equivalents, choose color schemes, change font sizes, etc.
Often models are run in "batches" to explore changes to a few parameters or conditions. For each figure the same process is required and rarely repeated EXACTLY.
One of the huge advantages I see for a project like FREEWAT is to make a template/wrapper that generates equivalent figures for multiple model runs. Assuming the model output is in the same format (binary head file, stream gauge files, etc), the user could simply point to the relevant files for each model and have an equivalent figure... same contour intervals, same color scheme, same symbols for wells, etc.
This functionality alone would motivate me to leave ESRI and use FREEWAT for all my post processing.
