I just installed version 0.5.3. I haven't used Sigil in a bit, but I know that there used to be a Validate option in here somewhere, and now it's gone. According to the User Guide, it should be under the File menu - it definitely isn't there.
Is this a known issue? If so, any idea when it will be resolved?
If I'm just being obtuse, where is the Validate option?
Thanks!
