Spectacle: selecting a region in an already taken screenshot

[Clemens Zeidler]

I am a KDE user over 10 years and I first like to thank everybody 
involved for their great work and for improving my productivity in my 
daily work!

I would like to contribute to the KDE project and was looking for a good 
issue to start with. One thing that always annoyed me, and I think is a 
relative easy task to start with, is the missing functionality to select 
parts of an already taken screenshots in Spectacle. For example, after 
taking a screenshot I would like to be able to select a portion of the 
image to copy it into another application.

I know that there is the rectangle function to take a screenshot. 
However, sometimes you need to take a screenshot quickly with a single 
key press and IMHO the rectangle feature is not optimal for that. 
Furthermore, I found it a bit difficult to discover this feature (only 
noticed it when looking for it just now, normally I always press the 
screenshot key and do the detour through an image editor).

From my point of view its also more natural to first take a full 
screenshot and then select the needed region. This would also make it 
possible copying multiple parts out of the same screenshot. This feature 
would be complementary to the existing rectangle function.

Do you think being able to select a region in the main window would be a 
good addition? I haven't thought about any details yet since I first 
like to get some feedback if this feature is desirable at all or if it 
already has been rejected for other reasons.

Best,
