When I set Show jump arrows and unset Show when registers are pointing to a visible address, the space allocated appears to be large enough for both, although only one thing is enabled.

@10110111, that is intended behavior, as register badge is drawn inside jump arrow area (on the left side of the first line)

Toggling Show when registers are pointing to a visible address while Show jump arrows is set will not change the space/area allocated.

It's not drawn when it's disabled, is it?

[shahrilnet]

Register badge is drawn inside jump arrow area, so there is no effect on area allocated if either the badge is drawn or not.

Jump arrow area is always going to be initiated as this size (https://github.com/eteran/edb-debugger/pull/731/files#diff-4af38e37cb69a85d76c168f3230a7adeL1650)

Unless I misunderstood what you're saying just now 😅

Ah, so you made it more economical... But don't you think it's not very nice when the arrows go over the badges, like in the following screenshot?

@10110111 that is a good catch (doesn't appear in my test 😅)

thank you! will fix it soon
