Need to fix some issues

I used to love this app so much until the recent updates. Its pretty much annoying when you turn on the night mode for ePub books, theres this thick white margin. Its disturbing. With the past few updates, they also forego the ability to trim white edges and search function for pdf documents. The search icon on the bottom when opening the pdf document is pretty much useless. It was used to be functional. I hope they could fix these issues for the upcoming updates.
