DisplayMaid has apparently created a new workspace for every possible permutation of my display setup. This renders the utility almost completely useless to me (at least not without a great deal of tedious configuration to workaround the problem). Some possible ideas for addressing this problem and ones related to it:
1) wait some amount of time before automatically creating a new workspace to allow for plugging in and unplugging displays
2) provide an option to not automatically create new workspaces
3) permit workspaces to be deleted
4) allow for constraining workspaces to dimensions only rather than order (or better detect when the order is actually the same)
5) add a default workspace whose configuration is inherited by any newly created ones or provide some other kind of inheritance or copyability of an applications list
6) allow multiple applications to be selected added to the application list simultaneously (then I could keep a folder of aliases to apps I want under DisplayMaid control).
