Hello there Stardock people,
It seems currently that the presence of a search bar in the Start10 menu is determined by the theme in use, with only the 'Windows 10 style' theme removing the bar entirely. This means that if I use any different theme I will always get a Start10 searchbar (correct me if I'm wrong!). However, I'm quite fond of the new taskbar search feature, and it's mildly clunky to have both the taskbar search functionality exist alongside the Start10 search functionality if I'm using one of the latter themes (in my opinion, at least). Whilst this is by no means a massive problem, it is unsightly, and my suggestion would be to have the option to remove/add the searchbar in the Start10 menu, independent of the theme being used.
Apologies this is a large request in response to an only minor inconvenience, but I thought I'd share it anyway! Aside from this, I'm enjoying the software massively; the original start menu was quite unbearable.
