SLP update discussion

We're planning to do S.L.P. Raspbian image update.
Known bugs (v0.2.3):
- FIle manager in Admin panel is using some external JS scripts. When StereoPi admin panel is accessed within a network without Internet, admin page design is broken. We are plan to copy all JS onboard.
- Expand root partition from 2Gb to 4 Gb (so users can install other software). Fix FAT32 auto format according to new 4 Gb size.
- If one of the cameras is disconnected (bad ribbon connection etc.), sometimes system became inaccessible over network.
- Current video stream splitting (for simultaneous stream to browser, RTMP, recording etc) logic is based on internal UDP data flow. This will be changed to shared memory approach to remove performance bottleneck at high resolutions.

If you've found other bugs - please post them here, and we'll add all of them in our to-do list. We will be pleased if you can describe all steps needed to repeat a bug.

Wishlist (collected from suggestions in this thread):
- Video recording button, current video recording status indicator
- Add "basic presets" for the video (resolution/bitrate/FPS), keep advanced settings
- Move "settings" JS tab to the separate page

I would add that it would be nice to have a button to record a video more easily, like the photo button does.
It would be even better if this button show the current recording state.

Today, I thought that perhaps you could also add the "classical" 24/25/50 fps video framerates in the selection menu.

Ok. But what if the user will decide to set FullHD at 50 fps? I think we need to do either "simple presets" (locking resolution+FPS), or "advanced settings" with some checking logic (like prohibiting 50 FPS for FullHD). Our experience shows, that at the beginning users try to set the maximum available settings for all options, and these settings exceeds hardware abilities.
So we have a choice here: either do our interface user-friendly, or give a flexibility and full control on all options.

You already have the possibility to set 1080@60
To reduce the risk of bad parameters, proposing presets might be a good idea, but I wish the advanced options would still be accessible some way.

Also, maybe it would be better to have the whole configuration in a separated page in multiple columns — I find it a bit hard to use in practice, especially on mobile device on the field — which in addition will give a good feedback on whether or not you clicked on the save button by returning to the main page.
