Hello everybody, For anyone interested in the option to compare two Lyx documents there is the opportunity to donate some money to develop such feature. The link in the Lyx webpage to get more information is: http://www.lyx.org/Donate This feature will be developed by Lyx's developers as soon as It reaches the minimum money to get the project started.
More precisely, the projects aims at compare two documents and generate a third document where the differences between the two documents will be highlighted using the track change feature (Menu "Edit->Change Tracking->Enable Change Tracking" if you don't know about it). So you would have to open the menu "File->Compare two Documents" then select the two documents with a file dialogue one after the other and 'voila', LyX will generate the third document and open it automatically for you. At present, there are 1270 euros available but the project needs still 730 euros to being accepted. In conclusion, if you are interested in this new feature and you wish to donate a bit of your spare money this project allows you to do so :-) Best regards, Silvio
