I've updated to v2.0 with a minimum of problems. (BTW, if the Kindle gives an "update not successful," disable the JBpatch items that are active.)
I noticed a problem last night--I was trying to rename files in a CBZ and it would extract the CBZ file fine but wouldn't rename the files. This is after running the rename script on its own several times. Here's how the directory structure ended up looking like:
Once I made it look like this, the rename script worked fine.
I simply renamed the ZIP file to CBZ without checking the contents.
I've been doing a lot of reading from one directory and have noticed after a couple hundred pages Komic slows down, so I have to return home and select the folder and start reading again. Is this normal?
