The Toggle Issue Comments userscript doesn't hide comments by default, which makes perfect sense. However the check mark (tick) symbol only appears to the right of a category after clicking a category of comment to hide that category, which I find very unintuitive and in fact the exact opposite of what I'd expect.

For example if Reviews (outdated) has a check mark next to it, it is more logical to expect that outdated reviews would be displayed rather than hidden, because check marks universally have a positive connotation. The only category of comment which gets this right is Hide +1s, because it makes it clear that when you select that category, the comments are hidden rather than displayed.

A similar problem is that the categories are emboldened when selected, and again except for Hide +1s this is counter-intuitive.

So I'd suggest one of two things:

1. Prefix every category with Hide , or
2. Swap the behaviour so that when the category is displayed (not hidden) the font is bold and the check marks are displayed, and Rename Hide +1s to +1 comments.

The first is slightly ugly, but the second could confuse some people who already adapted to the existing behaviour. Pick your poison, or maybe come up with a third approach which has neither of these problems ;-) Either way, I really think it needs to be made more intuitive, and the inconsistency between Hide +1s and all the others fixed.

Having said all that, this is a totally awesome extension, so thanks a lot for writing and sharing it!!
