ETextViewer

ETextViewer is a straightforward and user-friendly application that comes in handy for those who want a simple yet comprehensive tool to create, edit and store text files or books, as well as bookmark the most important ones at a click away.
It's wrapped in a clear-cut and tidy with a word editor and a toolbar that provides the most commonly used functions for faster access. The app features a bookmark system, opens large files and saves the cursor position for each document after it's closed.

Manage newly opened notes and favorite valuable ones

To make a new document you can either start typing or copying content from another source or open an existing item from the computer. Unfortunately, it only supports plain text files. The bookshelf function lets you view all the recently opened records, similar to the clipboard manager, which is cleared after a limited numbers of entries.
The bookmark comes in handy if there are more than one document for which you need to remember where you left off, as they save the cursor location value. There are up to five bookmarks you can use. Plus, the tool offers an option to scroll a specific number of lines and a delay time.

Customize the layout and content and look up for terms

You can search for particular words, save the current preferences, hide the toolbar, as well as change the background and frame colors. From the menu, the app lets you set the page margins, customize the font type, style, size and tint, and increase and decrease the font, useful for those with poor eyesight.
However, the basic interface doesn't provide functions to insert images, symbols, date and time, along with word alignment, bullet lists handy to quickly organize items, and highlight to easily find terms. Also, it would've been nice if the tool offered a save function, so you can open them in other programs after they are edited.

Conclusion

All in all, EtextViewer is an accessible and intuitive application designed to create, edit and store documents with various purposes, manage them in a bookshelf and add important ones in bookmarks. During our testing, it didn't consume too many resources nor encountered errors.
