I have been working on creating my own custom panel of brushes over the past few days.
I have saved it fairly often. I have even done a fairly recent system backup to time machine, though the file I deleted by mistake was more recently saved to my computer than that backup.
I was wanting to delete a brush (I did the grab twice by mistake), I have deleted the panel. There seems to be no quick 'undo' for this action.
I can see something with the same name as my panel ('My Custom EF panel') in my finder (it seems to have no file extension name), with the first bit of the contents looking hopeful - for example 'Luma Invert Bristle' half way down is the name of a brush I created. An image of a sample from the top seen in a text editor follows (a click on the image will show the contents clearly)
My question is: How can I reliably get back to where I was?
Any help is gratefully appreciated.
