Tone colors in the text of the e-books?

Is it possible to get tone colors on the text in the Pleco e-books? I get the colors when I click on the words, but I would love to see colors automatically in the text. I guess it is not possible, but this software seems to have so many incredible features that I thought I should ask.

Any update on this? I really would love to be able to see full pinyin or just pinyin tone marks on the whole page, but I realize that this is difficult technically. However, would it be so hard to get tone colors on the whole text? Thanks!
