[QGIS-Developer] Locator search results - double click vs. single click

[Andreas Neumann]

Hi Nyall, 

Is there no technical reason for the double click? If not, then I would
suggest, single click would be better (if it is feasible to switch at
all). Most online tools (like Google search, or Web-GIS) have a single
click for the search results. I don't think that QGIS users care about
Qt creator's locator. >99% wouldn't even know that Qt creator exists. 

Personally, I don't have a strong opinion on it, but colleagues at my
employer asked my "why double click?" and I promised them to find out
why it is that way. They said: wouldn't it be nice, if QGIS would behave
like most other applications when it comes to search ... 

Thanks, 

Andreas
