Many thanks for this suggestion! Certainly there are possibilities for improvement of the user interface, especially with respect to importance values and toggles, because there is just too many of them packed into a single command. We have been thinking about making them accessible using a separate GUI widget, just like for closeness and planarity analysis.
In general the UI concept in EvoluteTools is to have separate commands for changing parameters and optimization, at least for those optimization commands that take a lot of parameters. This approach is not used for D.LOFT and T.MAP for the moment, because there are not that many parameters exposed to the user yet.
We have not been thinking about changing the functionality of the etOptimize button so far, because it is usually used for many successive clicks, for which it would be disturbing if it wouldn't optimize immediately.
Let's use this discussion thread to collect some further input and ideas what to improve.
