Found and fixed. I'll upload a new release by the end of the week, but for now you can just replace your ethervaneecho.exe with the one attached to this message.
Great support - thanks a lot!
possibility to configure the directory for saving the database
possibility to configure the directory for saving the application-settings (ini)
Could you explain why this would be useful? It'd help me design the best way to implement this. Echo already uses a fairly involved logic to figure out where to store the database and config (are we portable? Are we running from a removable drive? Is the removable drive read-only? etc.), and I have to be careful making any changes to these parts of the code.
I use some automatic mechanisms for my backups. Therefore I store all my application-configurartions in special folders.
Would it be sufficient if I added a command-line argument to specify the config and database directories? You could add it to the shortcut used to start Echo.
Yeah, that would be really nice

possibility to change shortcuts like F2
What would you use instead? I can easily add more than one shortcut for some functions. A complete keyboard customization would take more time. And there would be certain limitations, e.g. you cannot assign certain keys which are used when editing clips in-place or are necessary to navigate the tree, etc. It could be more trouble than it's worth.
I don't think it would be practicable to use more than one shortcut for one function. Let's leave it as that

do not autopaste items on pressing enter - only copy them to the clipboard (like ctrl+shift+c)
Disable pasting entirely, or just swap the function of (Shift+)Enter and (Shift+)Ctrl+C?
I do not need that (I like what Ditto does). From my point of view you may disable it entirely

But I think i'll be better to make it customizable.
always show date and time for last saved items instead of e.g. "8 minutes ago"
Preferences -> Display -> Friendly dates -> set to False
Oops - I have overseen that - sorry.
Again - thanks for this wonderful application and that great support!
