Personally I prefer the newer interface. I felt something similar to you when a company I worked for went from MS Visual Basic 3 to version 5 (they never used version 4). But I grew to prefer it.
Many Gambas users have been asking for a MDI style interface for some time. The control used by the IDE is in the
gb.form.mdi component. And you can use it in your own projects. However I would not say it is a true MDI interface. For that you would be able to resize child windows and drag them around. A better description would be a workbook interface. Something like you see in many spreadsheets.
As for your question
Sorry I do not think you can get the old interface back. But give the new one a try.
