Re: [e4-dev] Getting rid of the swt fragment e4.ui.widgets.fragment
|
Hi Kevin,
Thanks for this work - I highly appreciate it. After 0.9 is released we
should all get together and discuss how we can make such things possible
in the future - as you I'd also like to see many different
Eclipse-Themes poping up in future but to make this reality we need a
strategy.
