Can I get inline blame (like GitLens) on Webstorm?
Install plugin GitToolBox. It has the same functionality as VisualCode's GitLens.
File > Settings > Plugins > Marketplace
In Webstorm, you can get all the blames for a file with the option:
VCS > Git > Annotate
Inline blame exact to Gitlens is most probably not available as of now for Webstorm.
UPDATED: corrected name to "GitToolBox" from "Jetbrains Toolbox"
This can be achieved through the GitToolBox plugin, it provides the exact same functionality as git lens, finally I found it! This can be toggled from other settings> git toolbox global or git toolbox project (if you only want to configure per project) See screenshot
Install plugin GitToolBox for inline blame like GitLens.
