Screenshot enhancements

[humdinger]

The current revision is hrev30234.
I’d like to propose a few enhancements in the hope that some are deemed worth implementing.

Options -> Preferences

• The options panel should get its own panel in Preferences to set defaults. It’s a system setting IMO.
• Besides what’s now in the options panel, there should be default “Name”, “Save as” and “Save in” settings.

Screenshot app (first two suggestions also apply to the preference panel to be)

• Add a “Settings…” button after the “Save as:” drop-down that opens the Translator’s settings.
• Add a “Clipboard” in the “Save in:” drop-down.

• Make the screenshot image to the left react to mouse clicks:
  • right-click: context menu with
    • “Open with” and a submenu with all image/* supporting apps.
    • checkmarkable “Take whole Desktop”,
    • checkmarkable “Take active window” plus checkmarkable “Include window border”
    • checkmarkable “Include cursor”

The screenshot image should reflect those checkmarkable changes. So changing from "whole screen" to "only active window" etc. would be possible even after taking the screenshot.

• double-click: opens in the preferred app.
• drag&drop to save, right-drag&drop additionally offers file formats.

I think it would be useful to have the PRINT key just take a screenshot with the preference defaults as usual and have SHIFT+PRINT open the Screenshot app.
