Everyone is flipping out because of the new UI -and I can understand the strangeness of it for old users- but so far I didn't have any of the issues that many are reporting regarding the browser bugging out while trying to display the page (I'm on Firefox Quantum x64 v.65 fyi).
Also I've been reading people saying that they still use Internet Explorer... Really? Even Microsoft developers call it a 'compatibility tool' than a web browser. Use Firefox, Chrome, Opera or Edge!
Anyways, yeah. Eclipse UI? I guess it's fine. It needs more color schemes than 'day and night' though. It needs a green one.
