>>> My Info: Win7_64, Nightly 53, 32bit, ID 20161119030204 (2016-11-19) STR_1: 0. Open devtools -> options, set dark theme. 1. Open devtools -> scratchpad 2. Open split console, open filter bar in split console AR: It's not clear where I should place mouse pointer to start resizing console (same as bug ???????) ER: It should be easy tell where console frame ends (W/o explicitly thinking about it. That's UX) Note: Actually, it's also not particularly clear if in Step 1 I open inspector, but I thought that scratchpad case is more convincing, therefore I only mentioned that case.
