Because of some confusion and the possibility of personal opinions / prejudice affecting things, going forward the "thumbs up" (recommended icon) will only appear on application cards where it is either the recommendation of the application developer themselves to use the particular container that the template is using (eg: Radarr), or if they themselves are maintaining the applicable container (not necessarily the template) eg: MySQL
In terms of plugins, this means that NO plugins will have the thumbs up unless they are explicitly endorsed by limetech (Dynamix Password Checker, Dynamix WireGuard), or have the implied endorsement (Unassigned Devices).
This change has already been made on the apps, but since it is nearly impossible to research each and every application, it is quite possible for me to have missed setting something for the thumbs up. If as a template maintainer you feel I should have set something to have the thumbs up, send me a Private Message with an applicable link to where the developer of the app is recommending your container.
In no way shape or form does this mean that you should not install any of the other containers. This change may also be at odds with what is the "prevailing wisdom" on the threads here. EG: Plex recommends explicitly to install their official container. The prevailing wisdom on these forums is to install either the Binhex or LSIO containers. The presence of a thumbs up also does not imply that the template is the "best". There will be cases where it is advisable to not install the recommended version because others are "better" (eg: Emby if you want to use hardware transcoding you would want to install the LSIO version)
While this change may be disappointing to some of the prolific template authors here, it is really the only fair way to handle things.
