Usability/design of tabs

[pablotheissen]

As much as I like the tabbed interface, the usability is not very high:

• the color difference between active and not-active is not big enough
• the tabs are cluttered with the X symbol for closing; only show the X while hovering the tab
• the color when hovering the active tab is the same as the not-active tabs. Does a color change when hovering the active tab even make sens? No other software does that.
• hovering non-active tabs doesn't lead to a color change as it does in almost every other software.
• rounded tabs don't work well in Windows, as nothing else is rounded (anymore)

Proposal:

• less round tabs
• active tab light color
• background tabs dark color
• hover over background tab: slightly lighter color, but not as light as active tab
• hover over active tab: no color change
• darkest color should be lighter than the active tab color as it is now, so you can read the black font more easily

Can be marked as duplicate of (take your pick): #343, #559, #743, #898.

@kjk most of above sugestions have actually been implimented and as @SumatraPeter has identified the above recomendations were also duplicated elswhere

[GitHubRulesOK]

As suggested these points are discussed elsewhere especially in #559 so closing as duplicate to be consolidated with that
