Change deletion method for filters

Instead of "Warning: Once deleted this filter cannot be restored", why not just send them to the recycle bin?

Today I deleted some test filters that were not useful.
The filters were in the same folder where I had useful filters too.

One or two times happened that FF was a little slow to relocate the filters after deletion.
This is what happened:
- I deleted a filter.
- Then I clicked on another filter that was below the previous one, to delete that filter too.
- As I said, FF was slow relocating the filters after deletion. My deletion request arrived before the relocation.
- FF relocated the filters, sliding the list of one position, and considered the wrong filter instead of the one I clicked.
- I got the usual warning message. I noticed it was the wrong filter, and it was fine.

But let's suppose that I didn't read the message well, or that the two filters had a very similar name and I clicked yes without understanding it was the wrong filter.
Then the filter would be gone without any chance to take it back.

Then, like uberzev said, wouldn't be better simply sending the file to the recycle bin?

When we delete a filter, the filter simply disappears from Filter Forge.
It doesn't go to Windows trash bin.
And there is no trash bin inside FF.
We get instead a message like the one below:

Oh! I understand now, the problem is that FF does NOT send the filter to the trash bin as it happens with most of the software, sorry that I was wrong thinking that the filters was sent to the trash bin, and this is why I did not understand it, now I know that I really never knew what happened to deleted filters until now.

I agree that the filters deleted should be sent to the trash bin instead of deleting them forever in case you delete it by mistake
