### Problem Description

I have 36 profiles.

10 of them (and growing) are for sorting subscriptions by last update, and I frequently move subscriptions from an older one to a newer one, for which this dropdown is helpful, but it is too short and my mouse wheel has gone bad.

Most of the other profiles have longer names and usually with emojis to give them an icon in the profile dropdown, which makes them too long to fit where "All Channels" fits.
"+most important" → "+most impo…"
"⚗ 0 Sciences and habits" → "⚗ 0 Scienc…" (maybe that 0 was kept by mistake)
"⚗ Sciences and habits" → "⚗ Science…"

### Proposed Solution

Make the drop-down longer and wider.
