Guide editing improvements and feedback

Hi, as a new user, I have some feedback about site utility for editing guides and the like.

• First, the ability to ctrl/⌘-K a link is really nice, but is currently limited to comments and cannot be used in guides, so please consider implementing it in guide editing as well.
• Comments made on an article can only be edited within five minutes of posting, which seems like an arbitrary and extreme limit to me. I recently commented on a repair article and had something more to add after posting, but by the time I was done formatting the original comment, I had to make a new comment because editing the first was disabled. Please consider extending this limit or changing comment editing to wiki-style, as guide editing operates.
• Lastly, when I edited this guide the other day to clarify that each replacement part was optional (as a guide for multiple different repairs which also includes a contact cleaning guide), I looked on the pending changes page which said that this edit "result[ed] in no net change and should be denied." This might be due to the "optional" toggle being such a small change that it was not classified by the system as a change.

I'm looking forward to fixing things for years to come. If this isn't the right place to post, please tell me the right one. Thanks for reading.
