Thanks, brucelee, that sounds like the best solution for now.
Yes, the lines in the TOC are very small, but I found it is still doable to tap the right one. Still, it would make sense to make the lines a bit bigger indeed, but in your new version I had only 8 lines in Landscape mode, and 11 in Portrait, and I would like to see a bit more than that. My preference would be to have something like 20 lines in Portrait. A TOC should give you an overview of what is in a book, and therefore should not be spread over too many pages.
Even better: make the size of TOC entries/the number of entries configurable; in that way everyone would be able to set the best value for themselves. But I have no idea if something like that would be doable for you

.
And once again: thanks for all the good work you put into CoolReader. It does improve the reading experience!
