Maybe I am alone who do not like the dark theme.
you can put a preference to switch it back.
But to me it is too late for such change. I am sure there are UI widgets/projects which looks horrible in dark. And people probably test them in pharo 6 before this change. So they will be very surprised.
no, dark theme is around since 3 years and is very depurated. In fact, many people already use it as they preferred theme.
Also I am really wondering that this decision was not publicly discussed. We should vote for such kind of changes.
no, this is not how it works.
We do not vote: most of the decisions are made by consensus and there is also the board who takes some decisions without asking because we pursuit an objective: for example we did not ask anybody if they wanted a new browser, we (the board) decided that Nautilus was not good enough and then we pushed for Calypso.
