Should I store entire objects, or pointers to objects in containers?
...nary note here...
On my last big project, my central data structure was a set of fairly straightforward objects. About a year into the project, as the requirements evolved, I realised that the object actually needed to be polymorphic. It took a few weeks of difficult and nasty brain surgery to fix ...

Keyboard shortcut to change font size in Eclipse?
...turned out to be that eclipse-fonts appears to affect only the "Text Font" setting rather than being aware of the font setting used in the current window.
