Components
This app is a full-featured open source not taking application. With it you can tag, search and send your notes, in addition to basic functionality such as creating, deleting and editing notes.
Proposal
The developers of OI Notepad should add the "minute read" feature to the note taking application. A tab or an option should be developed in the settings menu where a user can toggle like the word count on simple note.
Mockups / Examples
This feature will be added on the main page. You will need to highlight all text then the minutes read will calculate the time used in finishing up. 
Benefits
Users of the OI notepad application while putting down their presentation will be able to adjust their to-do lists, etc. to give them edge over the problem of running out of time during a presentation as the users will be able to give the approximate minutes or hours it will take to cover the note.
