Hi Aaron,

thanks for your detailed feedback. But it's growing over my head. Posting to 
the list is a great way to get my attention, but a terrible way to track 
issues that will need some time to resolve.

Now the feature tracker is not really suitable for this type of feedback, 
either. So let's try a wiki page. Since our own wiki hosting on SF.net is 
unbearably slow for editing (I'm so much looking forward to migrating that!), 
I've set up a page at https://community.kde.org/RKWard , and copied in most of 
your mail as a start. Meik, please add your stuff, too. Feel free to 
restructure.

I'm "watching" that page, so I will be aware of updates. All interested others 
are encouraged to do so, too. Forums might be a good way of tracking ideas, 
too, but the wiki simply was easiest to set up, right now.

Well, actually, there is a way. I sort of agree it may be a tiny bit 
unintuitive that you'd need to change the bottom-most control before clicking 
on any file name, though...

Yes, that makes a lot of sense, and is easy to do. So: done.

Yes, it would be good, if the enlarged font size would be saved. Two notes to 
make your life easier, today:

- Use Ctrl + Scroll-wheel (or whatever the equivalent may be on Mac) to adjust 
font size _very_ quickly.
- To get saved font size (and other customizations), here's a totally 
intuitive solution (ahem): Open a script editor. Go to Settings->Configure 
Editor, and make adjustments. Quit RKWard and restart. You should now see the 
new font size in both script windows, and the console.

Not to say that this solves, everything, but dragging out graphics (to file 
browser, or openoffice) works just fine, here. What are the symptoms on Mac, 
when you try to do so?
- Do you see a drag symbol / mouse pointer at all?
- Does the drag symbol disappear when leaving the RKWard window?
- Does the target refuse to accept the drop?

Yes, the decimal places are downright bugs, caused by using paste(), without 
format(). I've only learned that trick, recently...

Regarding the table layout: Controlled by rkward/pages/rkward_output.css . I'm 
no good at this, so if somebody would like to suggest a better layout...

Thanks again. There's no getting better without criticism.

But also, again: Let's try to make most of this discussion happen on the wiki 
page, above, turn other things into specific feature requests and bugs. There 
is no way to take care of all this within a few days. Discussing it in a wiki 
is no perfect safe-guard against bit rot, but discussing it via email, only, 
simply means some things _will_ be forgotten.

Regards
Thomas
