Version 2015.2.623.1 is the latest version. The Search window size and position are not remembered from one Search to another, let alone across executions. Please enhance. This suggestion seems to think it was done ... but if it was, it is now "undone": http://justdecompile.uservoice.com/forums/113277-justdecompile-feature-suggestions/suggestions/2853134-remember-screen-size-and-position
Some further Search enhancements:
1. Allow specification of case-sensitive or case-insensitive searches
2. Allow whole word only vs embedded in any part of the search string. In other words, search for "zap" with whole word only set would find "zap", "my zap", "his zap too", etc but not find "ourzap also", etc.
3. Draw up/down arrows in the headings of the Search results columns when they have been clicked to sort on that column.
