A long time ago, when Carl proposed the box selection cue (every selected object is enframed by a dashed box), I did not want to make this the default because I found it to be too intrusive. However, since then I grew to like this more than the default selection cue (every selected object has a diamond mark in the top left corner) and I find that I use the box selcue all the time. It's not so intrusive once you get used to it, and it gives a much better idea of the object extent and is nice for aligning things. Also, previously the selcue was only displayed in selector, where the scale/rotation handles make the selcue box a bit redundant; now however the selcue is displayed in most other tools that have no other handles around the selection.
Hence a question: would you agree or disagree if I make bbox selcue the default?
In case you don't know how to change it: Preferences > Tools > Selector, change "Per-object selection cue" from "Mark" (current default) to "Box".
