Re: Screen Curtain and Virtual Review: new versions are out #addonrelease



A proof of concept is a product that demonstrates an idea. In this case, NVDA issue 7857 deals with a suggestion to add screen curtain functionality to NVDA, and this work is being done by a developer in Europe.

The whole idea behind Screen Curtain add-on was to gather feedback from the NVDA community about this very feature. Based on feedback from users, this European developer made some changes to this feature which is slowly taking shape at the moment.

In fact, Screen Curtain isn’t the first proof of concept add-on. That honor belongs to Control Usage Assistant (now discontinued), an add-on developed by me that added context-sensitive help messages for various controls. Nor Add-on Updater will be the latest proof of concept add-on that has graduated to stable release status, nor Windows 10 App Essentials the only one where the add-on is used to do early field testing for eventual NVDA pull requests. In case of Add-on Updater, it is the realization of NVDA issue 3208 (an issue I myself wrote) that advocated adding add-on update feature to NVDA, and I’m actively working on a pull request to make that into reality. Regarding Windows 10 App Essentials, one or more important features from that add-on has just been transferred to NVDA, and will show up as part of upcoming 2019.1 release (specifically, in NVDA 2019.1, you won’t need Windows 10 App Essentials to benefit from improved usability of various time pickers in Windows 10; speaking of features, emoji panel support was originally part of my add-on until it was transferred to NVDA in 2018.3).

My sincere apologies for my tone.

Hi Joseph,


Just exactly what does 'proof of content' mean?  I went to the add on page and it really doesn't say exactly except that it 'addresses core issue 7857.' What is that issue?

Hi all,


I’m delighted to announce the release of Virtual review 2.4 and Screen Curtain latest snapshot build (note that Screen Curtain is a proof of concept add-on). In case of Virtual Review, version 2.4 includes latest localizations from many language communities.


As always, the new updates are just an update check away (via Add-on Updater, which itself will get an update very soon).
