[Github-comments] [geany/geany] Shared search for values on 'Find' / 'Replace' / 'Find in files' (#2320)

I think all these 3 dialogs should share the same 'search for' value and history.

For example, if I do a search for 'foo' and then decide I want to do a replace of 'foo' with 'bar', it would be good if the replace dialog had 'foo' in there already. (I realize if I leave the last search result highlighted it would, but I may not do so)
