I think that quick spelling and grammar corrections would be a great addition to the Diarium. Diarium does support spell checking, but to correct the word you have to right click on every single word one by one and then click on desired correction option. I would like to propose a quick correction system similar to Google Docs. In Google Docs spelling correction works in the same way, but in addition to the manual spelling correction it supports dedicated spelling and grammar correction mode. In Google Docs you can either press f7 or click on a dedicated button on toolbar to open the spelling and grammar correction window. Spelling correction window is a small window in a top right corner of the screen. It has several buttons that allow you to quickly go to previous or next misspelled word as well as two buttons to ignore error or accept suggested correction. When the error correction was accepted or ignored it automatically moves to the next error. All of the buttons in this window also have keyboard shortcuts. For tab accepts current suggested correction. This allows extremely fast spelling correction. In Diarium after typing i have to right click each and every single spelling error one by one to fix it. In Google Docs most of the time i can just open spelling correction and press accept a bunch of times to fix all spelling in file automatically. Or even fix every error at once. This spelling correction window also has an option to fix every error at once automatically.

In essence i want following feature. A dedicated button and shortcut that enables spelling correction mode. In this mode a small overlay window or section appears somewhere on the screen. When this mode is enabled it will automatically move text cursor to the first spelling error in the text. This section should have buttons that do following actions:

Go to next spelling error
Go to previous spelling error
Ignore current error and go to next spelling error
Apply suggested fix to current error and go to next error
Automatically fix all errors by applying to them suggested fix

Maybe it could also contain fix suggestions for the currently selected error. By that i mean suggestions that appear in the proofing section of the context menu when you right click on the word with error. If one of the suggestions is clicked in this window this suggestion is applied to fix the current error and the correction windows goes to the next error.

Basically i want this feature to work exactly as the original one does in the Google Docs.

Here is the the post that explains how this feature works in Google Docs: https://support.google.com/docs/answer/57859?hl=en&co=GENIE.Platform%3DDesktop
