2nd Request//Just Purchased Theme/Where is the support ?

I see a few dozen other support request answered since I put my request in early this morning, as a matter of fact mine have now wrapped around to the 2nd page… I have spent hours searching thru prior support answers before putting in my Q’s. I have about 30 hours working with this theme and some weaknesses of the product are becoming apparent…I am not a newbie. I have been a webmaster for about six years. I have used a lot of themes. I don’t think my questions should stump the support team.

I’ll pose them again:
1) How do you change the opacity level on Fullscreen slider, when you hover to click to link. The design element you have in place ( a large round colored ball) is enough of an indicator that an event will take place on click). Can you please tell me how I can turn off/down the opacity.

2) How do you disable lightbox on single post which uses featured image. I am surprised by the hundreds of requests for information in the support forum on how to do this. This translates into a design flaw in my book, Hopefully your working on something. I see a lot of goofy instructions that you provide users that goto in Quick CSS , some work, some don’t. I tried about six different suggestions. None worked. You really should have a simple way to turn on or off light box. Sorry to vent, but how do you disable lightbox on single post which uses featured image from media library

3) Where is information on changing font sizes for header, body, post. There has to be a simple way to change font size like you change font colors. Again, it seems like this is very convoluted process when compared to other themes.

4) Do you have a short code or a page template which will provide a category listing.

thanks
