I love that as a 'non-tech' person, I was able to rebrand our intranet with the help of our graphic designer (she has a great eye for what colours to use). I had to reference support blogs a few times, but there wasn't anything I didn't feel comfortable doing. I also really like the support that is available. They get back to you very fast and help work issues out. And honestly, most of my issues were that I wanted to something different, not that an issue with the software. We were able to successfully rebrand our intranet.
I like the ability to create different applications and that you can be pretty creative if you put your mind to it. We created a "shout out" app and didn't need to do anything special. It was as simple as adding certain fields to an app and adjusting the layout. Once you start to use the software a bit more, you realize most of the applications are the same base.
Although the simplicity is great, when it comes to the theme design, there are some items connected together that I wish weren't for example, if you change a colour of a title it could also change the colour in the mega menu. My designer also wanted more ability to change icons around, without having to do that for coding. A little more ability to customize would be nice.
The theme editor was also confusing at first and I had to some trial and error to figure out what items were affected.
The other annoying thing is that if you want to move files from one app to another or into a new site, you have to download everything and re-upload. I found the multi-upload feature hard to use too, so I ended up adding most files one by one. Moving 200 + files that way is very time-consuming, although worth it in the end!
