The current formatting for highlighted text within Zoho Flow is just a color change of the text itself, no highlighting as would be traditional (both in other Zoho apps and in almost all other software UIs):

This is extremely subtle and not a lot harder to see, especially when compared to the stark difference in highlighted text in most UIs:

This is especially an issue when trying to highlight just a few characters. The lack of the clean, high-contrast highlighting that we're all used to makes it harder than necessary for those of us with normal sensory capabilities. I would imagine it's even worse for those who require enhanced accessibility features.

True, this is a minor annoyance for most, but it seems like a totally unnecessary one.

Please consider changing this alternatively-styled subtle highlighting of selected text for a more traditional, high-contrast style.
