Its a very nice extension, however after tens of scratches, the app will start to slow down and may consume to much memory. Touch screen gets slower and slower and finally unusable.
Can you please add there a hard memory purge or a reset? Some part of the code needs fixing.
I checked to use two separate vertical arrangements but slowly freezing usability will follow. Basically, app needs to restarted and the scratch is working fast and smoothly but over the time it will slow down significantly. Some part of it may leave images in the memory perhaps and when there are coming more, the extension starts to struggle. Or it might be more complicated issues with the touch screen setup?
SetEraserMode is not helping or solving the issues, nor does Reveal.
It would need some sort of Clear -command, which would put the ScratchCard state to the early app starting point, flush all the cards etc (i don’t exactly know what happens in the background or where these images are stored).
But I feel that all the serial scratches are still on the card screen, somewhere behind others and app is then having around 100 pictures in the same screen and then android is starting to struggle.
