Recent update ruined the app

This update was awful! First they released it with a myriad of bugs, broken features and disappointed customers. I waited to update to see if they fixed their issues.

Just updated and very very sorry I did! Still a major lag. Removed a ton of features like the side bar controls. To highlight a character takes you about 7 clicks and if you mess up its about 14 more to fix it.

It went from being one of the best programs to one of the absolute worse.

Edit: Thank you for the updates, it is back to working normal. It has taken a while for me to get used to it but that is my fault not theirs, I am not that tech savvy and hate change lol. I highly commend this app for cross stitching from a pdf file or diamond painting from a pdf file of a cross stitch chart.

Why would a company mess with something that worked so great. On July 3rd my beloved ezPDF Reader updated and the new one stinks. Please change it back!!!

Search function

Edit: thank you so much for the recent update that fixed all the issues. This is a pleasure to work with again!

This update was certainly not an upgrade. Very disappointed with the search function. Not case sensitive? Really? What’s the point? Also, could the highlight color be any lighter? I’ll be finding another app to use.
Not to mention how ridiculous it is to have to swipe to highlight a square instead of touch. I used to use this app for cross stitch but no more.

At least you’ve got the case sensitive search back but this is still a very frustrating experience. A once enjoyable hobby of cross stitch is now a chore. Please bring the old ezpdf perfect functions back!
