Seeing marks, ideally in the gutter, but maybe as a highlight or something, would be helpful. This apparently existed at one point (https://github.com/vscodevim/Vim//commit/713f30a1a8f4923dfc2e7b0cbceffce78ab83c01#diff-a7723f32fe6b05e135838f84e5c23c0fR870), but decoration options have gotten richer and we can put it under a setting.

Sometimes there are so many files that I can't find out if there are some docs or images in my repository that aren't referenced by other files.

So I was wondering if it could create a file from command palette in a specified path which listed all the unlinked files and images by wiki-link or markdown-link to let me know all the files that are not linked, so that I can link them or delete them

🚀 Feature Proposal

Adding leading zero in the question number will be an awesome feature for file explorer to sort files by the name.

how to use gui in the AidLearning?how to custom the gui?

Hi, I am developer of VS Code and I am currently going through those extensions which has custom welcome experience (notifications / views) on install. VS Code provides Settings Sync feature OOB and users can have their machines in sync using this feature. So, when user sync such extensions with custom welcome experience, they should not be seeing welcome experience again in their other machines.

I would like to request a little more distinction in the syntax highlighting for css variables.
