It has been said that the ability to switch from the Dark UI to the original lighter UI may be dropped in future releases.

The Dark UI as it currently exists does not work for all users. For some it causes eye strain and depression. Some dialogs are unreadable and some icons are not recognizeable.

I understand that maintaining two UIs require more resources.

However, if only one UI is to be maintained I feel that the one requiring 3rd party software and possibly licensing fees is the one that should be dropped.

I understand that money may have already been spent towards licensing fees. However, that should not be considered as justification to continue spending money for future releases.
