request: ability to add files to .gitignore directly from the unstaged changes list

[eso]

Is your feature request related to a problem? Please describe.
i frequently don't know what i need to have in .gitignore until after i've been working on a project for a bit, and while i can edit the file by hand it's much more convenient to deal with it in the place where i found the problem (i.e. the unstaged changes list)

Describe the solution you'd like
i'd like to be able to select a file (or files, but right now you don't seem to have multi-select) and use the context menu to add them to .gitignore, in addition to the delete option

Describe alternatives you've considered
using a different client? not having a convenient feature? i can't think of a reasonable functional alternative

would be cool if you can edit the line before adding it to .gitignore.

e.g., i want to ignore a whole directory, so i would click on a file -> add to .gitignore -> change from path/file to path/*. similar with file endings "*.pdf" etc.
