Misc UI Suggestions

[SilverMarcs]

Would you consider moving searchbar to the titlebar? Perhaps add some fuzzysearch suggestions to the popup there.

Also, how about turning the profile button on titlebar to a generic user icon like on the MS Store app? This could reduce redundancy of having avatar icon in two places on the same window (sidebar and titlebar) At its current state, it looks somewhat out of place and the size of the whole button is also unusually large.
