This problem didn't start with this build, but I don't know exactly when it started so I'm just gonna throw it here in the hopes that it gets seen.
ctrl/cmd+d, used to select the next occurrence of the current selection, doesn't respect the "whole word" flag in your find settings (although it does respect the case sensitive flag).
This is a very noticeable problem now because of the new match_selection feature (which also ignores it, but defaults to true instead of false). It would be logical for "select more" to always select the next "highlighted" bit of text, and for the behavior of both to be consistent and user-definable.
Is there some setting I'm missing for this?
